Description of the Invention (/) The present invention relates to a liquid crystal display, and in particular to a surface-stabilized cholesterol-type liquid crystal with high A polychromatic liquid crystal display made by a transmissive color filter. As the line width of integrated circuits is getting smaller and smaller, more complex circuits and more data can be placed and stored in smaller spaces than ever before, which makes development light, thin, short, visible, and easy to use. Electronic devices have become the market trend. Among them, in order to realize the visibility function in a limited space and a plane, the use of a flat-panel display has become the most choice. At present, there are many types of flat-panel displays in the market. However, considering the cost and practical considerations, most commercial products still use liquid crystal displays (LCDs) as display elements that implement visibility functions. There are many types of liquid crystal displays widely used in the industry today. Depending on the contained liquid crystal molecules and the development principle, various liquid crystal displays also have their advantages and disadvantages, and their applicable scope. Among them, the surface-stabilized cholesteric texture (SSCT) liquid crystal material is a material with the advantages of memory, power saving, wide viewing angle, high brightness, and high contrast, so it is often used in the manufacture of display images. The refreshing rate is not high, and among the components that need to be used for a long time, such as electronic document display screens, electronic indicating boards, and so on. In the initial state, the SSCT liquid crystal molecules are in a chaotic arrangement. However, when an external electric field is applied, the SSCT liquid crystal molecules will have a certain degree of order under the action of the external electric field, and will reflect part of the band of incident light. Therefore, the ability of SSCT-type liquid crystal molecules to reflect incident light, Ί1 丄 LL——1 _, —— Order '1.V' (please read the precautions on the back before filling this page). Yinli Factory 4 32 2 5 0 30S9twf.RTFc / 006 A7 B7 V. Description of the invention (厶) It depends on the ordering of molecules. Its gray level can be controlled by the difference of electric field energy. In addition, no polarizer is required in the SSCT type LCD panel, so the manufacturing cost is low, which makes its commercial application potential greater than other LCD displays. At present, when the industry uses a SSCT type liquid crystal material to make a polychromatic liquid crystal display, the method used is to stack several layers of SSCT type liquid crystal panels that display different colors of light together, using the additive effect of light. Sex 'to achieve the purpose of displaying color. For example, a piece of SSCT type liquid crystal panel for displaying blue light is stacked on a piece of SSCT type liquid crystal panel for displaying yellow light, and a black absorbing layer is used as a bottom layer. Since the SSCT type liquid crystal molecules are transparent in a chaotic configuration In addition, blue and yellow are complementary colors to each other, so it can display images including white, black, blue, and yellow under the control of driving voltage. In theory, only three layers of SSCT-type LCD panels used to display the three primary colors of red, green, blue, and optical are stacked together, and the image can be displayed in full color. However, when two or more liquid crystal display panels are combined, the first problem to be faced is how to properly align the liquid crystal panels of each layer. In order to accurately display the image in color, the pixels used to display the same position on the image in each layer must be completely aligned in the visual direction, otherwise the image will be distorted, and even if the LCD panels are stacked accurately, It is difficult to avoid the problems of parallax effect and partial weight. Therefore, in addition to increasing the difficulty in manufacturing, this pair of steps is bound to be expensive to manufacture and not necessarily convenient to use. And because the switching signals required to drive each layer of SSCT-type LCD panels cannot be the same, it must be designed and manufactured for each layer of SSCT-type LCD panels (please read the precautions on the back before filling in 4 pages) 'Order Central Bureau of Economic Affairs Printed by Shelley Consumer Cooperative ^ 432250 3089twf.RTFc / 006 B7 V. Description of the invention (3) The stand-alone driving signal circuit has greatly increased component cost and component thickness. Furthermore, in order to avoid the parallax effect, the thickness of the liquid crystal substrate is theoretically not greater than the pixel pitch, so that the pixel pitch is directly related to the resolution of the liquid crystal panel, because its size cannot be smaller than the thickness of the substrate , And subject to the manufacturing technology of the substrate. Therefore, the number of colors that can be displayed by a display element composed of a stack of several SSCT-type liquid crystal panels and the resolution of the element itself are mutually limited. In addition to the SSCT type liquid crystal panel, another PSCT (polymer-stabilized cholesteric texture) type liquid crystal panel having similar properties to the SSCT type liquid crystal is also often used as a material for a polychromatic flat display. In the conventional practice, the spiral distance of the liquid crystal molecules in a specific area is fixed to some specific predetermined ridges by using ultraviolet and temperature modulation to reflect certain predetermined colored light to display a polychromatic image. the goal of. However, this method is difficult to repeat, and the polyester network dendritic structure formed by it to stabilize the arrangement of liquid crystal molecules is very fragile, which makes the stability insufficient. Furthermore, trying to form regions displaying different colors at the same time on the same LCD panel not only limits the resolution, but it is very difficult to design and manufacture the driving circuit, so the manufacturing cost is also very high. It can be known from the above that the conventional manufacturing methods of SSCT or PSCT type liquid crystal display panels, or because of the alignment process, or because of the design and fabrication of the driving circuit, or because of increasing the display resolution, or because of the process of fixing the arrangement of liquid crystal molecules Not only is it technically facing a lot of difficulties, making the cost of manufacturing polychromatic liquid crystal displays with SSCT or similar liquid crystal materials 5 This paper standard applies to the Chinese National Standard (CNS) A4 specification (2 丨 called '公 楚)' — ~~ — (Please read the note ^^ on the back before filling this page)

Description of the Invention (Valley) Please refer to Figure 1, which shows one of the simple SSCT LCDs according to the present invention. Sectional view of the display. The main constituent structure of the SSCT-type liquid crystal device of the present invention includes a color filter film 5 having a high transmittance and a SSCT-type liquid crystal molecular layer 7. The color filter film 5 further includes different filter pixels such as a first filter pixel 5a, a second filter pixel 5b, and a third filter pixel 5c, which are respectively used for the second predetermined color light. The three predetermined color lights and the fourth predetermined color light pass through, for example, the red light, the green light, and the blue light in an RGB color filter. The SSCT-type liquid crystal molecular layer 7 uses the force generated between the liquid crystal molecules in the alignment film 3 and the SSCT-type liquid crystal molecular layer 7 as an anchoring force to fix the arrangement of the SSCT-type liquid crystal molecules, so that this liquid crystal panel can reflect. A first predetermined color light. Then, an electrode layer 2 for driving liquid crystal molecules in the SSCT-type liquid crystal display panel is clamped. The electrode layer 2 further includes an upper electrode 20 and a lower electrode 21. The upper electrode 2a further includes a first pixel electrode 20a, a second pixel electrode 20b, and a third pixel electrode 20c. A protective layer 5 is formed between the upper electrode layer 2 and the color filter film 5 to prevent the ionic impurities in the color filter film 5 from dissolving out, which will have an unfavorable effect on the liquid crystal. The above components are then packaged with a glass substrate 1. The black light absorbing layer 6 is placed on the bottom of the entire liquid crystal display panel 'to absorb incident light that is not reflected by the SSCT liquid crystal panel. When this liquid crystal display panel acts, an electric field is formed between the electrode layers by the driving signal, and the electric field controls the order of the liquid crystal molecules and controls the intensity, or gray scale, of the reflected light. The upper electrode and the lower electrode of each group in the electrode layer are respectively 8 —--- ΓL —, 1_r —__— ill · — — — τ (Please read the note on the backside before filling out this page) Paper size Applicable to China National Standard (CNS) A4 specification (2 丨 〇X 297 mm) A7 B7 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs P4 322 5 〇3089twf.RTFc / 006 5. Description of the invention (7) SSCT liquid crystal molecules The two sides of the layer correspond to the position of each pixel on the color filter film to control the gray scale of the pixel. Generally speaking, the driving signals of each LCD can use different levels of signals on each pixel to affect the arrangement of liquid crystal molecules in between, and produce a grayscale effect, such as 8 grayscales. The simple color liquid crystal display of the present invention, because one of the single-layer SSCT-type liquid crystal panels can only be used to reflect a single color light, such as yellow light, so under the control of the driver, the black, The yellow light reflected by the SSCT liquid crystal panel itself and the change in its gray scale, plus the red, green, and blue pixels of the color filter film 5, make use of the additive nature of color light to make the image almost full color. The type is displayed. Nowadays, because of the general SSCT type liquid crystal panel, the driving circuit is designed so that 8 gray levels can be displayed on the liquid crystal panel. Therefore, with the cooperation of the color filter film, 8 different gray levels displayed by each pixel can be used. Colored light, such that each pixel group composed of several pixels of different colors, including the colored light displayed by 3 pixels, for example, under the effect of optical addition, and a certain distance, Utilizing the illusion of human vision, it can display 8X8X8 = 512 different light color changes, so each pixel group can be regarded as a display unit with 512 color light changes. This group of pixels is regularly arranged on the color filter film in a certain order, and the image is displayed in a nearly full-color manner.
