Description of the Invention: [Technical Field] The present invention is a dual mode liquid crystal display, especially a dual mode liquid crystal display that operates in a dual mode, a monochrome reflection mode, and a color penetrating mode. . [Prior Art] The increasing use of displays in various electronic buttons has made it necessary for display manufacturers to strive for components that provide better performance. Performance parameters include power consumption, resolution, frame refresh rate, cost, and readability in daylight. Display manufacturers use a variety of techniques to improve the performance of these performance parameters. One of the techniques is to use a transflective LCD. Each pixel of the transflective LCD has a reflective part and a transmissive part. The portion also includes a sub-pixel (sub_pixel) as well as the reflection portion. Each pixel has a filter (c〇i〇r mter) for imparting color to the pixel. Further, each sub-pixel is arranged horizontally or vertically, so that three or more sub-pixels are required to present a color in the LCD. In the above method, the filter is placed over the penetrating portion and the reflecting portion. Therefore, the light passing through the filter is diminished, making the reflection mode obscured and not easy to read. In addition, the backlight requires more power in the penetrating mode to achieve a still resolution display. • In addition, using sub-pixels configured horizontally or vertically will result in lower resolution. What's more, switching all color components in the LCD requires high frequency and high power consumption. Looking at the above discussion, there is still a need for a technology that can produce high-resolution LCDs that can be read in the dark. In addition, there is a need to develop an LCD that requires only low power and a low image frame rate. The present invention achieves the above requirements. SUMMARY OF THE INVENTION It is an object of the present invention to provide an LCD that provides better resolution than existing LCDs. Another object of the invention is to reduce the power required to illuminate the LCD. Another object of the present invention is to reduce the image fran rate of an LCD. Yet another object of the present invention is to provide a display that is readable by daylight for an LCD. SUMMARY OF THE INVENTION The present invention provides an LCD having a filter plate only above the penetration of a pixel so that it can be read under ambient light. Yet another form of the invention eliminates the need for a black matrix mask that is typically used in the manufacture of filters. In addition, the present invention provides diagonal pixels to enhance the resolution of the LCD in the color penetration mode. In addition, another aspect of the present invention allows light to be switched between two colors, while a third color (generally green) is always present, thereby reducing the LCD's approach to hybrid field sequential methods. The required image update rate. Another form of the invention is to produce color from a backlight, thereby eliminating the filter. Yet another version of the present invention uses filters only above the green light 200823554 pixels, thereby eliminating the need to use additional reticle to fabricate the filter array. [Embodiment] Various embodiments of the present invention relate to a liquid crystal display (LCD) that can operate in a dual mode, a monochrome reflection mode, and a color transmission mode. Those skilled in the art will recognize the various modifications and variations of the preferred embodiments and the general principles and features described herein. Therefore, the invention is not limited to the embodiments presented, but should be defined in the broadest scope of the claimed principles and features. The first diagram shows a cross section of a pixel 100 of an LCD in accordance with an embodiment of the present invention. The pixel 1 〇〇 includes a liquid crystal material 1 〇 4, a pixel electrode 106, a common electrode 108, a reflective part 110, a transmissive part 112, substrates 114 and 116, and spacers. 118a and 118b, a first polarizer 120, and a second polarizer 122.

In an embodiment of the invention, the pixel electrode 1〇6 and the common electrode 108 can be formed using oxidized ___Tift Oxide, ITO). In addition, each pixel is provided with a pixel electrode, and the common electrode 108 is shared by all the pixels in the LCD. In an embodiment of the invention, the reflecting portion 11 is electrically conductive and can reflect the surrounding Light 124 is illuminated to illuminate pixel 100. The reflection portion 11 is made of metal and electrically coupled to the pixel electrode 1?6, thereby providing a potential difference between the reflection portion 110 and the common electrode 1?8. The penetrating portion 112 transmits light from the light source 102 to illuminate the pixel 100. The substrates 114 and 116 enclose the liquid helium material 104, the pixel electrode 1 〇6, and the common electrode 1. In an embodiment of the invention, the pixel electrode 106 is disposed on the substrate 114, and the common electrode 108 is disposed on the substrate 116. In addition, substrate 114 includes switching elements (not shown in the first figure). In an embodiment of the invention, the switching element may be a Thin Film Transistor (TFT). In addition, a drive circuit 130 transmits a signal associated with the pixel value to the switching element. In an embodiment of the invention, drive circuit 130 uses a low voltage differential signaling (LVDS) driver. In another embodiment of the present invention, a transistor-transistor logic (TTL) system that simultaneously senses voltage increase and decrease is applied to the drive circuit 13A. In addition, the ''timing controller'' 140 encodes the signal associated with the pixel value as the signal required for the diagonal penetration of the pixel. In addition, the timing controller 140 has a memory that allows the LCD to self-update when the signal associated with the pixel is removed from the timing controller 140. In one embodiment of the invention, spacers 118a and 118b are placed on top of reflector portion 110 to maintain an equal distance between substrates 114 and 116. In addition, the image of the first polarizer 120 and the second partial film 122 is included.

像素100係由光源1〇2或周遭光線124照射。通過像 素1〇〇的光的強度係藉由像素電極106與共用電極1〇8之 間的電位差所決定。在本發明的一實施例中，當像素電極 106與共用電極log之間沒有被施加電位差的時候，液晶 材料104係處於非定向（disoriented)狀態，通過第一偏光片 120的光會被第二偏光片122所阻檔，而當像素電極106 與共用電極108之間有被施加電位差的時候，液晶材料104 係處於定向（oriented)狀態。液晶材料104的方向性會讓光 通過第二偏光片122。The pixel 100 is illuminated by a light source 1〇2 or ambient light 124. The intensity of light passing through the pixel 1 is determined by the potential difference between the pixel electrode 106 and the common electrode 1〇8. In an embodiment of the invention, when no potential difference is applied between the pixel electrode 106 and the common electrode log, the liquid crystal material 104 is in a disoriented state, and the light passing through the first polarizer 120 is second. The polarizer 122 is blocked, and when a potential difference is applied between the pixel electrode 106 and the common electrode 108, the liquid crystal material 104 is in an oriented state. The directivity of the liquid crystal material 104 allows light to pass through the second polarizer 122.

The pixel 1A includes a penetrating portion n2b and a reflecting portion 110. In an embodiment of the present invention, the penetration portion A Uii-c respectively imparts damage to the green, monitor, and red light to form a color pixel if the RGB (Red One Monitor) color system is followed. Further, if different color systems are selected, the penetrating portions 112a-c can impart different color bars 9^' like blush, fiber, blue and white or other colors. Further, the reading 11/1 '1 1 3 3, 114a gives green light, the penetrating portions ii3b and 114b impart blue light" and the penetration 113a and 114c gives red light to the pixels. In addition, different thicknesses "呌/慝光A sheet 200823554 is placed over the penetrations 112a-c to reduce or increase the color saturation imparted to the pixels. Saturation is defined as the intensity of a particular level of color in the visible light spectrum. Further, in the different embodiments of the present invention, 'colorless filters 2' to 2d can be placed on the reflecting portion 110. In various embodiments of the invention, the thickness of the colorless filter 202d may vary from zero to other thicknesses of the filters placed over the penetrations n2a-c. In an embodiment of the invention, the penetrating portion 112a represents a diagonal strip of one of the three colors of the color pixel. Similarly, the penetrating portions n2b and n2c represent the diagonal bands of the other two colors of the color pixels. The diagonal band allows the resolution in color-penetration mode to be close to the resolution in monochrome (black and white) reflection mode. The color penetration mode requires high resolution because the human visual system can detect horizontal and vertical lines when visualizing the image. In another embodiment of the present invention, the vertical band of color can be used, and the resolution of the horizontal direction of the car can be changed, and the resolution of the less vertical direction can be changed, compared with the use of the diagonal band. The amount of light transmitted from the source 102 through each of the penetrating portions 112a-c is determined by the exchange element (not shown in the second figure). Then, the amount of light transmitted through each of the transmissive portions H2a-C determines the color of the color pixel. In addition, the shape of the penetrating I5 a e and the filter may be hexagonal, rectangular, octagonal, circular, or the like. Further, the shape of the reflecting portion 11 () may be a rectangle, a circle, an octagon, and the like. In addition, the reflecting portion '11' blocks the light transmitted to the diagonal band and does not transmit to the pixels of different colors. For example, the reflecting portion 110 blocks light and tooth penetration along the penetrating portions 112c and U3C. 11 11 plus or 112a. Alternatively, a black matrix reticle 200823554 2; between a pixel and a light sensitive area of a pixel, ", I." may be used. In an embodiment of the invention, the black matrix reticle 203 is omitted. The schematic diagram shown in the first figure illustrates the role of the pixel 100 in the monochrome reflection mode according to an embodiment of the invention. Since only the monochrome reflection mode is explained in the third figure, the figure Only the reflection portion 11A is shown. The pixel 100 can use a monochrome reflection mode with an external light source, in the present invention

The colorless filter 2〇2d is used to maintain the attenuation and path difference of the ambient light 124 as the attenuation and path difference in the color penetration mode. The reflective portion 11() of the pixel 100 reflects the ambient light 124 to the substrate 116. In an embodiment of the invention, the potential difference (v) is applied to the pixel electrode 1〇6 electrically coupled to the reflection portion 110 and the common electrode 1〇8. The liquid crystal material 104 is oriented in accordance with the potential difference (v). Therefore, the directionality of the liquid crystal material 1〇4 is rotated by the plane of the surrounding light 124, allowing light to pass through the second polarizer 122. Therefore, the directivity angle of the liquid crystal material 1 〇 4 determines the brightness of the pixel 1 ,, and thus affects the light-emitting intensity of the pixel 10 。. In an embodiment of the invention, the pixel 1 〇〇 can be a generally white liquid crystal embodiment. In this embodiment, the axes of the first polarizer 12 and the second polarizer 122 are parallel to each other. The pixel electrode 1〇6, and the common electrode 1〇8 are applied with the maximum threshold voltage to block the light reflected by the reflecting portion 11〇. Thus pixel 100 appears to be black. Alternatively, the pixel 1 is a general black liquid crystal. In this embodiment, the axes of the first polarizer 120 and the second polarizer 122 of the 200823554 are perpendicular to each other. The pixel electrode 1〇6, and the common electrode 108 are applied with a maximum threshold voltage to illuminate the pixel 1〇〇. The schematic diagram shown in the fourth diagram illustrates the effect of the LCD in color pass mode when a partial filter method is used in accordance with an implementation of the present invention. Since the color penetrating embodiment has been previously described, in the fourth figure, only the penetrating portions 112a_c are shown. As shown in the fourth figure, on the substrate ία, the light guide sheets 404a, 404b, and 404c are placed for the penetration portions 112a, 112b, and 112c, respectively. Light source 102 is a standard backlight. Light 402 from source 1 〇 2 can be aligned using a collimated light guide (c〇nimating HgM) or a lens. In an embodiment of the invention, light 4〇2 from source 1〇2 passes through first polarizer 12〇. The first polarizer aligns the plane of the light 4〇2 to a specific plane. In an embodiment of the invention, the plane of the light 4〇2 is calibrated in a horizontal direction. Further, the second polarizer 122 has a polarization axis (axis 〇fp〇iarizati〇n) in the vertical direction. The penetration portion n2a_c transmits the light 402. In an embodiment of the invention, each penetration has an individual exchange element. The switching element controls the intensity of light passing through the corresponding penetration. In addition, the light 402 passes through the liquid crystal material 104 after passing through the penetrating portions n2a_c. The penetrating portions 112a, 112b 舆 ΐ 2 are provided with the pixel electrodes 106a-c. The difference in the turtle position at the gates of the pixel electrodes 16a-c and the common electrode 1〇8 determines the directivity of the liquid crystal material 1. Next, the directivity of the liquid crystal material 104 determines the intensity of the light 402 incident on each of the filters 4〇4a-c. In an embodiment of the present invention, the green filter 4〇4/ is placed over the squeezing 112a, and the illuminating filter 404b is placed over the penetrating portion 12 200823554 112b. And the red light filter 404c is placed on the penetration portion ii2c. Each of the filters 404a-c imparts a corresponding color light to the color pixels. The light imparted by the filters 404a-fc determines the chrominance value of the color pixel. Chroma contains color information such as hue and saturation of a pixel. Further, if there is ambient light 124, the light reflected by the reflecting portion 11 〇 (as shown in the second and third figures) provides the luminous intensity of the color pixel. This luminous intensity increases the resolution in the color penetration mode. The luminous intensity is a measure of the brightness of the pixel. The schematic diagram shown in the fifth diagram illustrates the effect of the LCD in the color penetrating mode when using the method of mixing the field sequential according to an embodiment of the present invention. Since the color penetrating embodiment has been previously described, only the penetrating portions 112a-c are shown in the fifth figure. In one embodiment of the invention, light source 102 includes LED strips, such as LED group 1, LED group 2, and the like (not shown). In an embodiment of the invention, the horizontally arranged LEDs are grouped together and one LED group is connected to the other to illuminate the LCD. Alternatively, vertically arranged LEDs can also be brought together. The LED groups are illuminated in a sequence, and the illumination frequency of an LED group can be between 30 frames per second and 540 frames. In an embodiment of the invention, each LED group includes a red LED 506a, a white LED 506b, and a blue LED 506c. In addition, the red light 1^: 〇 506 & and the white light LED 506b of the group 1 are turned on by time t 0' to t 2, and the red light LED 506a and the white light LED 506b of the LED group 2 are甶time t = 1 to t « τ

Similarly, the blue LED 506c and the white LED 506b of the Led group 1 are turned on by time 5 to 10, and the blue LED 506c and white light LEd 506b of the LED group 2 are time t = 6 to t 2

Similarly, all blue and white LEDs of the other LED groups function in a sequential manner. The red light LEd 506a, the white light LED 506b, and the light monitoring LED 506c are configured such that the red light lEd 506a and the blue LED 506c illuminate the penetration portion penetrating portions 112& and 112c, and the white light LEDs 5b6b illuminate the penetrating portion 112b. In another embodiment of the invention, the LED group can include red, green, and illuminating LEDs. The red, green, and blue LEDs are also configured such that the green LEDs 5〇6b illuminate the penetrating portion 112b, and the red lights lEd 5〇6a and blu 1Ed 506c illuminate the penetrating portions 112& and n2c, respectively. In an embodiment of the invention, light from source 1〇2 passes through first polarizer 120. The first polarizer 12 杈 aligns the plane of the light 5 〇 2 to a specific plane. In an embodiment of the invention, the plane of the light 502 is in a horizontal direction. Further, the second polarizer has a polarization axis in the vertical direction 2. The penetrating portion U2a_e transmits the plate. In the case of the present invention, the female one penetration portion 112a-c has individual exchange elements. The outer [father] element controls the intensity of the color light component by controlling the light passing through each of the penetrating portions 112a-c. In addition, the light 502 passes through the liquid crystal material 1〇4 after being transmitted through the tooth-permeable portions 112a-c. Each of the penetrating portions 11 =, 112b and i12c has its own pixel electrode 1〇6a-c. The potential difference between the pixel electrodes 16a-c and the common electrode 1A8 determines the directivity of the liquid crystal material 忉4. In an embodiment using red, white and blue LEDs, 14 200823554 then the directivity of liquid crystal material 104 determines the intensity of light 5 〇 2 incident on green light filter 504 and transparent spacers 508a and 508b. The intensity of light passing through the green filter 504, and the transparent spacers, 5〇8a and 5〇8b, determines the chromaticity values of the color pixels. In the embodiment of the present invention, the green light filter 504 is placed corresponding to the penetrating portion 112b, and the diffusing portions 112a and 112c are provided without a filter. Alternatively, the transparent portions 508a and 5b8b may be used for the penetrating portions 112a and 112c, respectively. Green light filter 504, transparent spacers 508a and 508b are located on substrate 116. In another embodiment of the present invention, a magenta light filter, a light sheet, can be placed over the transparent spacers 508a and 5081?. In an embodiment of the invention, between time 1: one () to t = 5, when the red LED 5〇6a and the white LED 5〇6b are turned on, the penetrating portions 112a and 112c are red, and The green light-passing sheet 504 imparts green light to the penetrating portion 112b. Similarly, between time 6 and time t11, when the blue LED 506c and the white LED 506b are turned on, the penetrating portions 112a and 112c are red, and the green light filter 504 imparts green light to the penetrating portion 112b. . The color imparted to the color pixels is formed by a combination of the color lights from the penetrating portions I12a-c. Further, if there is ambient light 124, the light reflected by the reflecting portion 110 (as shown in the second and third figures) provides the luminous intensity of the color pixels. This luminous intensity increases the resolution of the color penetration mode. The schematic diagram shown in the sixth diagram illustrates the effect of the LCD in the color penetration mode when the method of diffraction is used, according to an embodiment of the present invention. Since T. ' has previously described the color penetrating embodiment, only the penetrating portions 112a-c are shown in the sixth figure. Light source 102 can be a standard backlight. In an embodiment of the invention of 15 200823554, light 602 from source 102 can be divided into green component 602a, blue component 602b, and red component 602c by a diffraction grating 604. Alternatively, light 602 can be divided into a spectrum of colors, while different portions of the spectrum of light can pass through each portion of penetration 112a-c, respectively, by a micro-optical structure. In an embodiment of the invention, the micro-optical structure is a flat film optical structure having a small lens group that can be embossed or introduced into the film. The green light component 602a, the red light component 602b, and the blue light component 602c are guided to the penetrating portions 112a, 112b, and 112c by the diffraction grating 604. The components of the light 602 pass through the first polarizer 120. The first polarizer 120 aligns the plane of the light components 602a-c to a particular plane. In an embodiment of the invention, the plane of the components 602a-c of light is aligned in a horizontal direction. Further, the second polarizer 122 has a polarization axis in the vertical direction. The penetrating portions 112a-c allow light components 602a-c to pass therethrough. In an embodiment of the invention, each of the penetrating portions 112a-c has a separate switching element. The switching element controls the intensity of the light passing through the corresponding penetrating portions 112a-c thereby controlling the intensity of the color component. Further, the light component 6〇2a_c passes through the liquid crystal material 104 after being transmitted through the penetrating portions 112a-c. The transmissive portions 112a, 112b, and 112c have pixel electrodes 106a-c, respectively. The potential difference between the pixel electrodes 16a-c and the common electrode 108 determines the directivity of the liquid crystal material 104. Then, the directivity of the liquid crystal material 104 determines the intensity of the light components 602a-c passing through the second polarizer 122. The intensity of the light components 602a-c passing through the second partial light-receiving sheet 122 determines the chromaticity of the color pixels. In addition, if there is ambient light, the light reflected by the reflecting portion 110 (as shown in the second figure and the third figure of 200823554) provides the luminous intensity of the color pixel. This intensity of light increases the resolution in color penetration mode. As described in the present invention, the wear-through portions of the pixels are arranged diagonally, rather than in a vertical or horizontal configuration as in the previously known LCD. The penetrating section is diagonally arranged to improve resolution compared to previously known LCDs, thus providing better display functionality. • In addition, ambient light enhances the luminance of color pixels in color-through mode. Therefore, each pixel has both luminosity and chromaticity, which increases the resolution of the LCD. Therefore, the number of pixels required for a particular resolution will be lower than previously known LCDs, thereby reducing the power consumption of the LCD. In addition, the interface based on the transistor logic (ttl) can be used to reduce the enthalpy compared to the interface used in previously known LCDs. 〇 Power consumption. In addition, because the timing controller stores signals related to pixel values, the LCD can be optimized for self-renewal, thereby reducing power consumption. In various embodiments of the invention, thinner filters can be employed to deliver less saturated colors and more light. Therefore, various examples of the present invention can achieve the purpose of reducing power consumption as compared with previously known LCDs. In addition, in the embodiment of the present invention (as described in the fifth figure), green light or white light is always visible on the pixel 100, and only red light and blue light are switched. Under the display (fWd sequentiaj display), only the lower image update rate is required. While the preferred embodiment of the present invention has been described above, it should be noted that the present invention is not limited to the embodiments. Without departing from the spirit of the present invention and the scope of the present invention, as described in the scope of the patent application, the present invention may be modified, changed, changed, replaced and equivalent.
