Description
Technical Field
The invention relates to the technical field of display electronic products, in particular to a full-color low-power-consumption electronic thin film display device and method.
Background
With the development of science and technology and the improvement of the living standard of people, the display equipment which is visible everywhere in daily life of people is developed towards a lighter direction, and the flexible low-power thin film display technology gradually becomes a popular research direction.
For display devices, color display effect is a key display performance, and since display devices are available, people have higher and higher requirements for color representation of display devices, which also promotes the development of the electronic display industry. Saturation refers to the purity of a color, and monochromatic light of various colors in the visible spectrum is the most saturated color, and the more white light is incorporated into the spectrum, the less saturated the color.
Research on the human visual system shows that about 700 thousands of pyramidal cells are distributed on each retina of a normal adult, when a beam of colored light is emitted into the human eye, part of pyramidal cells are induced, and corresponding electric signals are transmitted to the brain, so that the human can have color perception. The light with different colors corresponds to different wavelengths, and for the light in different wave bands, if the light is emitted into human eyes under the condition of close distance, the color mixing can be generated due to the space color mixing effect of the vision of the human eyes, and the human brain perceives the color of the light corresponding to the different wavelengths after the space color mixing.
Disclosure of Invention
The purpose of the invention is: the electronic display film is composed of a color display layer and a saturation regulation layer, the color display layer reflects components with corresponding wavelengths in natural light to realize color display, the saturation regulation layer reflects white light with different degrees, the white light is mixed in color light reflected by the color display layer to realize adjustment of display saturation of the electronic display film, and then color expression of the electronic display film is adjusted to realize full-color display.
The color display layer is made by pouring reflective ink of four colors of cyan, magenta, yellow and black into the display micro-cavity.
The display microcavity of the color display layer is manufactured into a latticed rectangular half cavity on a substrate by a nano-imprinting technology, and color ink is filled into the half cavity and then is adhered to the upper saturation regulating layer.
The substrate for making the color display layer can be PET or glass.
The microcavity bodies of four colors on the color display layer are transversely arranged in sequence, the width-length ratio of each display microcavity is 1: 4, and the four transverse microcavities form a square display unit.
The saturation control layer is a switch array which is formed by etching a driving electrode on the ITO layer through laser and is made of PDLC materials.
The substrate of the ITO layer on the saturation control layer can be PET or glass.
The size of each small switch window of the switch array on the saturation control layer is the same as that of the display micro-cavity on the color display layer.
The saturation regulating layer regulates and controls the saturation of the display colors of the four reflective color printing inks respectively, and regulates the components of different colors in the display image, thereby realizing full-color display.
Because of the spatial color mixing effect of human vision, the distance between the adjacent display micro-cavities on the color display layer is very small, the color light reflected by each display micro-cavity and the color light reflected by the adjacent display micro-cavities can generate spatial color mixing, so that the human eyes can see the color after color mixing, the transmittance of a switch window on each display micro-cavity is respectively controlled by a switch array on the saturation regulation and control layer to change, and then the color contribution rate of each display micro-cavity to the spatial color mixing is changed, different spatial color mixing effects are generated, and full-color display is realized.

FIG. 2 is a schematic cross-sectional view of a display unit of the full-color low-power electronic film of the present invention;
Detailed Description
The technical solution of an embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the following examples are given for illustrative purposes only and are not to be construed as limiting the scope of the present invention, and that the skilled person in the art will be able to make various insubstantial modifications and adaptations of the present invention based on the above disclosure.
The utility model provides a full-color low-power consumption electronic film display device and method, the electronic display film comprises colored display layer and saturation regulation and control layer, as shown in figure 1, the composition of corresponding wavelength in the natural light is reflected to the colored display layer, because different wavelengths correspond different colours, realize the colour display from this, saturation regulation and control layer 5 reflects the white light of different degrees under the transmittance condition of difference, mix in the colorama that the colored display layer reflects, realize the regulation to the electronic display film shows the saturation, and then adjust the color expression of electronic display film, realize full-color display.
The color display layer is manufactured by filling reflective inks of four colors of cyan, magenta, yellow and black into the display micro-cavities respectively, as shown in fig. 1, and positions of the display micro-cavities corresponding to the four colors of cyan, magenta, yellow and black are shown in fig. 1, 2, 3 and 4 respectively.
The display micro-cavities of the color display layer are a plurality of latticed rectangular half-cavities with the same size manufactured on a layer of PET film or thin glass by using a nano-imprinting technology, four colors of reflective color ink are transversely and sequentially filled into the half-cavities, the width-length ratio of each display micro-cavity is 1: 4, as shown in figure 1, so that the four transverse display micro-cavities form a square display unit, and all the micro-cavities on the color display layer are filled with the color ink and then are adhered to the upper saturation regulating layer 5, as shown in figure 2.
The saturation regulating layer 5 is a switch array made of PDLC material, wherein a driving electrode is etched on an ITO layer which takes PET or glass as a base material by laser, each small switch window of the switch array can independently control the on-off and transmittance, and the size of each small window is the same as that of a display micro-cavity on the color display layer.
The saturation regulating layer 5 controls the proportion of white light in each display microcavity color in one square display unit by controlling the transmittance of each small switch window, so as to regulate and control the saturation of the display microcavity display color. Because the distance between the adjacent display micro-cavities on the color display layer is very small, the colors expressed by the four display micro-cavities in each square display unit can generate color mixing in space due to the space color mixing effect of human vision, so that the human eyes can see the colors after color mixing, and each square display unit can express full color by adjusting the saturation of the four colors in one square display unit, so that the whole display film can realize full-color display.
Because the electronic film in the embodiment adopts a passive display method of reflecting external natural light, backlight is not needed in the image display process, only the saturation regulation and control layer needs to be applied with voltage in the normal display process of the whole electronic display film, and the transmittance of each small switch window of the switch array is controlled, so that the electronic film has extremely low working energy consumption.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to be limited thereto.
