To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.
An embodiment of the present disclosure provides a display panel, a schematic cross-sectional structure of which is shown in fig. 1, and at least includes:
a glass substrate 1, a black matrix 2, and a pixel layer 3; the glass substrate 1 is provided with a black matrix 2, the pixel layer 3 is connected with the black matrix 2 and the glass substrate 1 so as to form a plurality of sub-pixel points 31 of the pixel layer through the shielding of the black matrix, and the pixel layer is made of red, green and blue color resistance materials; a blue color resistance filter structure 4 is disposed at a predetermined position of the black matrix 2 to filter out light transmitted through a predetermined angle range from sub-pixel points corresponding to the red color resistance material and the green color resistance material through the blue color resistance filter structure 4, wherein the blue color resistance filter structure is made of the blue color resistance material.
The embodiment of the disclosure utilizes the black matrix in the existing display panel structure, namely, the black matrix is provided with the blue color resistance filtering structure, so that the sub-pixel points corresponding to the red color resistance material and the green color resistance material and the light transmitted in the preset angle range can be filtered, when a user observes the screen at any angle, the L0 color deviation is the dark colors such as blue, the conditions such as red or purple do not exist, the display panel is simple to manufacture, the material is used as the pixel layer, the manufacturing cost is lower, the problem of the color deviation of the screen is solved by the simplest production process and the least manufacturing cost, and the product performance is improved.
The pixel layer is made of red, green and blue color resistance materials, and in particular, the color resistance materials can be color filter films.
The predetermined angle may be an angle formed by the user observing the display panel and the display panel, that is, an angle range in which the sub-pixel points corresponding to the red color set material and the green color set material can transmit light, for example, as shown in fig. 2, the sub-pixel points corresponding to the red color set material and the green color set material can transmit light within a certain angle range, and therefore, when the user observes within the certain angle range, the user may observe light of a color that the user does not want to see. Therefore, when the blue color resistance filter structure is arranged, the arrangement can be carried out according to a preset angle range.
For example, a blue color-blocking filter structure is disposed between adjacent pixel strips, the length of the blue color-blocking filter structure is greater than the length of the pixel strips, and each pixel strip is made of only one color of color-blocking material. As shown in fig. 3, each pixel band is made of a color-resistant material with a color, that is, includes a plurality of sub-pixel points (simplified in the figure, only 3 sub-pixel points are shown in one pixel band) made of the same color-resistant material, and the length of the set blue color-resistant filter structure at least exceeds the positions of the head and tail sub-pixel points in one pixel band.
For another example, as shown in fig. 4, a blue color blocking filter structure is disposed on the black matrix corresponding to the four vertex angles of each subpixel point, and the blue color blocking filter structure is cross-shaped with respect to the horizontal plane of the glass substrate, wherein a connection angle formed by an end point of a first side and an end point of a second side of any right angle in the blue color blocking filter structure and a connection line of center points of the subpixel points corresponding to the right angle has a predetermined degree. In the specific implementation process, four blue color resistance filtering structures corresponding to one sub-pixel point are not connected with each other, and any two adjacent blue color resistance filtering structures and the other two blue color resistance filtering structures are mirror images.
In a preferred embodiment, the predetermined degree may be 60 degrees. In a preset coordinate system relative to a horizontal plane where the glass substrate is located, an included angle between the first edge and the first coordinate axis is equal to an included angle between the second edge and the second coordinate axis, wherein the preset coordinate system takes the central point of the sub-pixel point as an origin and two lines parallel to the cross edge of the blue color resistance filtering structure as coordinate axes respectively. The principle of determining the predetermined degree as described above can be seen in fig. 5.
During specific implementation, the thickness of the blue color resistance filtering structure should be greater than or equal to the maximum thickness of the adjacent pixel band, the thickness of the blue color resistance filtering structure is as high as possible, but the display panel can be guaranteed to be in a better light and thin state within a reasonable range, and therefore, when the thickness of the blue color resistance filtering structure is set, light which is transmitted by sub-pixel points corresponding to the red color resistance material and the green color resistance material should be considered. For example, as shown in FIG. 6, the thickness of the blue color-resistant filter structure may be the same as the minimum thickness of the pixel strip of blue color-resistant material; in this case, the pixel strips of blue color-resist material may be integrally formed with the blue color-resist filter structure, i.e., by a Mask design.
For the blue color resistance filtering structure, a connecting line between the highest point in the thickness and the lowest point in the thickness of the adjacent sub-pixel point forms an angle of 45 degrees relative to the horizontal plane of the glass substrate, so that the best use effect is obtained by using the least color resistance materials and sacrificing the least screen thickness.
The above embodiments will be further described with reference to the display panel being used in a vehicle-mounted product.
In current vehicle-mounted products, the requirement of customers on L0 color cast is higher, and each visual angle in an L0 color cast picture needs to be blue or gray, so that the condition of purple or red is not accepted. At present, in order to meet the requirement of color cast, an E-Mode is generally adopted for a screen. However, the optical index (contrast) of E-Mode is lost more than that of O-Mode.
In view of the above problems, the embodiments of the present disclosure solve the problem of color shift redness under the L0 color shift picture by adding a special design of the Blue color resistance filter structure (i.e., Blue color resistance filter structure) and increasing the output of the Blue light component at an oblique viewing angle. Meanwhile, the color cast of the O-Mode is improved under the condition of keeping the advantages of the O-Mode optical index in technical effect by supporting the O-Mode and the E-Mode modes when the color cast is used in the Cell box, so that the requirements of customers in two aspects are met.
Example 1:
the traditional Panel internal CF section structure is composed of red, green and blue color resistors (i.e. sub-pixel points composed of three color resistor materials) arranged in a Stripe mode. When light is irradiated to the color resist, the color of the light through which the color resist can pass is displayed. When we look in oblique direction we can see the light refracted and scattered by each angle emitted by the red, green and blue color resistances. However, since red light has a higher refractive index than blue light, the red component seen by the naked eye increases and the blue component decreases at a larger angle in the oblique direction.
To compensate for this loss, the present disclosure employs a Blue color resistance filter structure that increases the exposure Pattern of the Blue Mask without adding a new Mask. When the naked eye observes perpendicularly, Blue color resists the filtration and is blocked by BM (black matrix) in BM below, can not cause the change of light, and the naked eye sees red, green, Blue light normally. However, when the human eye observes in an oblique direction, the Blue color resistance filter structure starts to filter red light and green light in the oblique direction, and allows the Blue light to pass through, so that the color shift effect in the oblique direction is improved.
In the specific implementation, the Blue color resistance filter structure has the same components as the Blue color resistance, is positioned below the BM and has a width smaller than that of the BM. As shown in fig. 7, the height of the Blue color resistance filter structure can be inferred from the simulation result that the color chip effect under a large viewing angle can be ensured when the Blue color resistance filter structure forms an angle of 45 degrees with the sub-pixel point, so that the height of the Blue color resistance filter structure is the same as the width of the sub-pixel point. Certainly, the height of the Blue color resistance filtering structure is the same as the width of the sub-pixel point, and the Blue color resistance height of the embodiment of the disclosure can be full of the Panel box thickness, that is, the space of the whole upper glass substrate and the whole lower glass substrate is fully supported by Blue. The person skilled in the art can adapt the height and width of the Blue color resistance filter structure according to actual needs, and it is within the scope of the present disclosure.
In the embodiment of the disclosure, the Blue color resistance filtering structure is added below the BM, so that the passing of oblique red light and green light is blocked while the passing of vertical light is not influenced, and the Blue light passes smoothly. The proportion of the blue light under the large visual angle is increased, so that the effect of adjusting the large visual angle color cast of the screen is achieved.
Example 2:
the implementation process of this embodiment is similar to that of embodiment 1, except that in embodiment 2, the Blue color resistance filtering structure is placed at four corners of each sub-pixel point. Since the most significant positions of color shift L0 occur are the four diagonal corners, and instead there is no color shift problem in the four diagonal directions, embodiment 2 of the present disclosure can increase the brightness in the four diagonal directions, i.e., the upper, lower, left, and right directions, compared to embodiment 1. The Blue color resistance builds a cross Pattern at each corner.
In the embodiment, according to the simulation result (the vehicle-mounted rule requirement is that Δ uv is less than or equal to 0.3), namely, the color cast problem is easiest in four angle ranges of 15-75 degrees, 105-165 degrees, 195-255 degrees and 285-345 degrees, the Blue strips are added in the oblique direction to filter the light rays in the oblique direction in the embodiment of the disclosure. Meanwhile, the openings in four positive directions, namely, the upper direction, the lower direction, the left direction and the right direction, are reserved, so that the light transmittance is increased, and the optimization of the optical effect is facilitated.
The embodiment of the present disclosure further provides an electronic device, which at least includes the display panel in the above embodiment of the present disclosure.
