Description
Technical Field
The present invention relates to a touch liquid crystal panel, and more particularly, to a touch liquid crystal panel based on COA technology.
Background
A Thin Film Transistor Liquid Crystal Display (TFT-LCD) is light, Thin, and small, and has the advantages of low power consumption, no radiation, and relatively low manufacturing cost, and thus occupies a dominant position in the current flat panel Display field.

Compared with the traditional liquid crystal panel, the liquid crystal panel adopting the COA technology has the advantages that the color filter is integrated on the array substrate, so that the problem that the color filter unit is not strictly aligned with the pixel electrode does not exist, the aperture opening ratio of the liquid crystal panel can be improved, and the brightness of the liquid crystal panel is increased. However, in the prior art, a plurality of Photo Spacers (PS) are disposed between the array substrate and the opposite substrate of the COA liquid crystal panel, and the photo spacers are designed in the non-display area of the panel, so that once the panel slides or vibrates during the manufacturing process or is moved to a position after the manufacturing process is completed, the photo spacers will be moved to the display area of the panel due to the substrate shift. In the COA panel, the photoresist spacers entering the display area may scratch the display area due to the small difference in the structure topography, which may damage the topography of the display area, distort the electric field, and so on. Since the main light blocking spacers are often placed in the blue sub-pixels, multiple small blue colors are usually present on the panel, which affects the display quality of the product.

Detailed Description
In order to make the present disclosure more complete and complete, reference is made to the accompanying drawings, in which like references indicate similar or analogous elements, and to the various embodiments of the invention described below. However, it will be understood by those of ordinary skill in the art that the examples provided below are not intended to limit the scope of the present invention. In addition, the drawings are only for illustrative purposes and are not drawn to scale.
Specific embodiments of various aspects of the present invention are described in further detail below with reference to the accompanying drawings.
Fig. 1 shows a schematic structural diagram of a touch liquid crystal panel based on COA technology in the prior art. Referring to fig. 1, the conventional touch liquid crystal panel includes a first glass substrate (such as a color filter substrate) 10 and a second glass substrate (such as a thin film transistor array substrate) 20. The touch liquid crystal panel receives light from the backlight module 30, and controls the direction of liquid crystal molecules by controlling the voltage between the two substrates, thereby realizing the brightness control of the pixels.
The first glass substrate 10 includes a substrate 102, a first alignment layer 104, a Black Matrix (BM) layer 106, and an Upper Polarizer (Upper Polarizer) 108. The first alignment layer 104 is disposed below the substrate 102 and covers a display Area (AA) and a non-display Area (also referred to as an "element Area") of the panel. Here, the display area and the non-display area are separated by a straight line L, and the display area of the panel is located on the left side of the straight line L for displaying images or pictures; the non-display area is located on the right side of the straight line L and used for placing control elements or circuit boards. The black matrix layer 106 is disposed under the substrate 102, and a Photo Spacer (Photo Spacer) PS is disposed on the surface thereof and protrudes toward the second glass substrate 20. The upper polarizer 108 is located above the substrate 102.
The second glass substrate 20 includes a substrate 202, a second alignment layer 204, a color filter layer 206, and a Lower Polarizer (Lower Polarizer) 208. Wherein, the second alignment layer 204 is located on one side of the second glass substrate 20 close to the liquid crystal layer. A conductive layer (such as ito) is disposed between the second alignment layer 204 and the color filter layer 206. A thin film transistor is placed under the color filter layer 206. The lower polarizing plate 208 is positioned below the substrate 202.
As described above, in the touch liquid crystal panel of fig. 1, although the photo spacers PS are designed in the non-display region, if the panel slides or vibrates during the manufacturing process, the first glass substrate 10 and the second glass substrate 20 will be relatively displaced, and the photo spacers PS will easily run to the display region of the panel due to the substrate displacement. Since the difference in the topography of the substrate structure is small, the photo spacers PS entering the display region scratch the display region, which may damage the topography of the display region, distort the electric field, and so on.
In order to solve the above drawbacks or deficiencies in the prior art, the present invention provides a novel touch liquid crystal panel architecture. Fig. 2 is a schematic structural diagram of a touch liquid crystal panel based on COA technology according to a first embodiment of the present invention. Fig. 3A and 3B are schematic diagrams illustrating states of the photo spacers of the touch liquid crystal panel of fig. 2 when the substrate is displaced.
Referring to fig. 2, in this embodiment, the touch liquid crystal panel of the invention includes a first glass substrate 10 and a second glass substrate 20. Similarly, the first glass substrate 10 includes a black matrix layer 106 and a first alignment layer 104 covering the black matrix layer 106. The black matrix layer 106 is positioned at a non-display region (i.e., right side of the straight line L) of the panel. The second glass substrate 20 includes a second alignment layer 204 and a color filter layer 206 disposed below the second alignment layer 204.
It should be noted that the first glass substrate 10 further includes a first photo spacer PS1 disposed on the black matrix layer 106 and protruding toward the second glass substrate 20. The second glass substrate 20 includes two second photo spacers PS21 and PS 22. The second photo spacer PS21 is disposed on the second alignment layer 204 and on the left side of the first photo spacer PS1, and the second photo spacer PS22 is disposed on the second alignment layer 204 and on the right side of the first photo spacer PS 1.
In this way, the second photo spacers PS21 and PS22 can be used as a left wall (left wall) and a right wall (right wall), respectively, and even if a relative displacement occurs between the first glass substrate 10 and the second glass substrate 20, the photo spacers PS1 will not enter the display area of the panel due to the substrate displacement. For example, when the photo spacer PS1 moves to the right, the photo spacer PS22 will form a stop, as shown in FIG. 3A. When the photo spacer PS1 moves to the left, the photo spacer PS21 will form a stop, as shown in FIG. 3B.
In one embodiment, the thickness of the first photo spacer PS1 is greater than the thickness of the second photo spacer PS21 or PS 22. The first photo spacer PS1 is used as a main photo spacer (main PS) to realize the signal sensing function.
In one embodiment, the color filter layer 206 includes a red filter, a green filter and a blue filter, and the first photo spacers PS1, the second photo spacers PS21 and PS22 are disposed in the blue filter region corresponding to the blue sub-pixel.
Fig. 4 is a schematic structural diagram of a touch liquid crystal panel based on COA technology according to a second embodiment of the present invention.
Comparing fig. 4 with fig. 3, the main difference between them is that the first glass substrate 10 and the second glass substrate 20 of fig. 4 have different photoresist spacers disposed. Specifically, the first glass substrate 10 includes two first photo spacers PS11 and PS12 disposed on the black matrix layer 106 and facing the second glass substrate 20. The second glass substrate 20 includes a second photo spacer PS2 disposed in the non-display region of the panel and disposed on the second alignment layer 204. The first photo spacers PS11 and PS12 are located on two sides of the second photo spacer PS2 respectively to form a displacement wall. Even if the first glass substrate 10 and the second glass substrate 20 are relatively displaced, the photo spacers PS2 will not enter the display area of the panel due to the substrate displacement.
In one embodiment, the thicknesses of the first photo spacers PS11 and PS12 are less than the thickness of the second photo spacer PS2, and the second photo spacer PS2 is a main photo spacer (main PS) to realize the signal sensing function.
Fig. 5 is a schematic structural diagram of a touch liquid crystal panel based on COA technology according to a third embodiment of the present invention.
Comparing fig. 5 with fig. 3, the main difference between the two is that in the touch-sensitive liquid crystal panel of fig. 5, the second alignment layer 204 of the second glass substrate 20 includes a recess 210. The recess 210 is located in the non-display area (right side of the line L) of the panel and corresponds to the position of the black matrix layer 106. The first photo spacers PS1 contact the bottom of the recess 210, and the two sidewalls of the recess 210 serve as a displacement wall when the first photo spacers PS1 move. Therefore, due to the existence of the recess 210, even if a relative displacement occurs between the first glass substrate 10 and the second glass substrate 20, the photo spacers PS1 will not enter the display area of the panel due to the substrate displacement.
Fig. 6 is a schematic structural diagram of a touch liquid crystal panel based on COA technology according to a fourth embodiment of the present invention.
Comparing fig. 6 with fig. 5, the main difference between them is that the black matrix layer of the first glass substrate 10 of fig. 6 includes a first black matrix unit 106 and a second black matrix unit 112 disposed at intervals, and the recess 110 corresponds to the recess region between the first black matrix unit 106 and the second black matrix unit 112. Photo spacers PS2 contact the bottom of recess 110, and the two sidewalls of recess 110 serve as a displacement wall when photo spacers PS2 moves. Therefore, due to the existence of the recess 110, even if a relative displacement occurs between the first glass substrate 10 and the second glass substrate 20, the photo spacers PS2 will not enter the display area of the panel due to the substrate displacement.
Fig. 7 is a schematic structural diagram of a touch liquid crystal panel based on COA technology according to a fifth embodiment of the present invention.
Comparing fig. 7 with fig. 5, the main difference between the two is that the black matrix layer 106 of the first glass substrate 10 of fig. 7 includes a recess 110'. Similarly, the recess 110' can prevent the photo spacers PS2 from entering the display area of the panel due to the substrate shift. In one embodiment, the recessed portion 110' of the black matrix layer 106 can be formed by an interference method, a half tone mask (half tone mask) method or a gray tone mask (gray tone mask) method.
The touch liquid crystal panel based on the COA technology comprises a first glass substrate, a second glass substrate and a display area, wherein the first glass substrate comprises a black matrix layer and a first alignment layer covering the black matrix layer, the second glass substrate comprises a second alignment layer and a color filter layer positioned below the second alignment layer, photoresist spacers are arranged on one side of the first glass substrate and one side of the second glass substrate, and a displacement retaining wall is formed by the photoresist spacers on one side of the two substrates, so that the photoresist spacers on the other side of the two substrates are prevented from entering the display area of the touch liquid crystal panel. Compared with the prior art, the liquid crystal panel is provided with the photoresistive spacers on the two substrates respectively, and the photoresistive spacer on one side is used as the retaining wall, so that the photoresistive spacer on the other side cannot slide into the display area of the panel, and the display quality of the product is improved.
Hereinbefore, specific embodiments of the present invention are described with reference to the drawings. However, those skilled in the art will appreciate that various modifications and substitutions can be made to the specific embodiments of the present invention without departing from the spirit and scope of the invention.
