Description of the invention: * [Technical field of the invention] The present invention is a dual mode liquid crystal display, especially a dual mode liquid crystal type, a monochromatic reflection mode and a color mode. monitor. [Prior Art] The increasing use of displays in various electronic components has led display manufacturers to strive to provide components with better performance. The performance parameter package includes 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 and the reflection portion also include a sub-pixel. A mother has a pixel (c〇i〇r fiiter) 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 light film system is placed above the penetrating portion and the reflecting portion. Therefore, the light passing through the light sheet is attenuated, so that the reflection mode becomes blurred and is not easy to read. In addition, the backlight 7 requires more power in the penetrating mode to achieve the display of θ and resolution. In addition, using a horizontal or vertical configuration of sub-pixels will result in a lower resolution. What's more, switching all the color slaves and 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 in daylight. Degree LCD. In addition, there is also a need to develop an LCD with only low power and low image frame rate. The present invention can clean up the above requirements. SUMMARY OF THE INVENTION [The present invention] It is an object of the present invention to provide a 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 frame rate of an LCD. Yet another object of the present invention is to provide a display that is readable by daylight for an LCD. The present invention provides an LCD having a filter only above the penetration of a pixel so that it can be read under ambient light. Another form of the invention is to eliminate the 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 version 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 method for hybrid field sequential. The required image update rate. Another form of the invention is the production of color by a backlight' thereby eliminating the filter month. Yet another version of the invention is to use a filter only on top of green 1354159 pixels, thereby eliminating the need to use an additional reticle to make the array of illuminators.

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) 71 surface that simultaneously senses voltage increase and decrease is applied to the drive circuit 13A. In addition, a 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 〇 4 〇 has a memory' allows the LCD to self-update when the signal associated with the pixel is removed from the timing controller 140. In an embodiment of the invention, 'spacers 11' and U8t) are placed 8 1354159. • are placed over the reflective portion 110 to maintain an equal distance between the substrates 114 and 116.

In an embodiment of the present invention, if the RGB '(red_blue-green) color system is followed, the penetrating portions 112a-c respectively impart green, blue and red light components to form A color pixel. Furthermore, if different color systems are selected, the penetrating portions 112a-c can be given different colors, such as red, 'green, blue and white or a combination of other colors. Further, the penetrating portion 113a and 114a imparts green light, and the penetrating portions 113b and 114b impart blue light, and the penetrating portions 113a and 114c impart red light to the pixels.

Saturation is defined as the intensity of a particular level of color in the visible light spectrum. Additionally, in various embodiments of the present invention, a colorless filter 202d can be placed over the reflective portion 110. In various embodiments of the invention, the thickness of the colorless tear sheet 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 1121) and 112c 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 illuminate horizontal and vertical lines when visualizing the image. In the other two examples of the present invention, a vertical band of color can be employed, and the degree of resolution in the horizontal direction can be changed as compared with the use of the diagonal band, and the degree of vertical direction is changed. The light source 102 is determined by the optical switching element (not shown in the second figure) transmitted through each of the penetrating portions U2a_c. Then, through each of the transmissive parts, the color of the mosquito color pixels is transmitted. The shapes of the portions 112a-c and the filter may be different from the shape of the circle, or the like. In addition, the anti-rectangular, octagonal, circular, human-angled, and similar cities may be rectangular, transmitted to the diagonal band of light, and will not pass, ping-reflected, 110 will block, for example, the reflection 110 will block the passage of pixels that wear different colors to enter the penetration (10) or 112a. Instead of the t/i center and the received light, a black matrix mask 1354159 203 or a gap between the pixel and the sensitive area of the pixel can also be used. In an embodiment of the invention, the black matrix mask 203 is omitted to enhance the reflectivity of the pixels. The schematic diagram shown in the third diagram illustrates the effect of pixel 100 in a monochromatic reflection mode in accordance with an embodiment of the present invention. Since only the single-color reflection mode is explained in the third figure, only the reflection portion 110 is shown in the drawing. The pixel 100 can use a monochrome reflection mode in the presence of an external light source. In the embodiment of the present invention, the ambient light 124 is incident on the reflection portion 11 through the colorless filter 202d and the liquid crystal material 104. on. The colorless filter 2〇2d is used to maintain the attenuation and path difference of the ambient light 124 with the attenuation and path difference in the color penetration mode. The reflecting portion 110 of the pixel 10 turns the ambient light 124 to the substrate 116. In an embodiment of the invention, a potential difference (v) is applied to the pixel electrode 1 electrically coupled to the reflection 110 and the common electrode 1A8. 6. The liquid crystal material 104 is oriented in accordance with the potential difference (¥). Therefore, the directionality of the liquid crystal material 1 〇 4 _ rotates the plane of the surrounding ray 124 to allow 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 而 and thus affects the light-emitting intensity of the pixel 100. 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 106, and the common electrode 1A8 are applied with a maximum threshold voltage to block the light reflected by the reflecting portion 11A. Thus pixel 100 appears to be black. Alternatively, the pixel 1 can be a general black liquid crystal. In this embodiment, the axis of the first polarizer 12A and the eleventh 1354159 polarizer 122 are perpendicular to each other. The pixel electrode ι 6 and the common electrode 108 are thinned to the 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 embodiment of the present invention. Since the color penetrating embodiment has been previously described, only the penetrating portions 112a-c are shown in the fourth figure. As shown in the fourth figure, on the substrate stack 16, the light-receiving sheets 404a, 404b, and 404c are respectively directed to the penetration portions ma, n2b.

Light source 102 is a standard backlight. Light 402 from source 1 〇 2 can be aligned using a collimating light guide or lens. In an embodiment of the invention, light 402 from source 102 passes through first polarizer 120. 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 is calibrated in a horizontal direction. Further, the second polarizer 122 has a polarization axis (axis 〇f p〇larizati〇n) in the vertical direction. The penetration e transmits light 402. In an embodiment of the invention, each of the penetrating portions has an individual exchange element. The exchange element controls the intensity of the corresponding penetration. In addition, the light 4 〇 2 is transmitted through the liquid crystal material, and is passed through the pixel electrode 106a_c. The potential difference between the ', the knife' is different...

In the case of the 荖, the directionality of the wide-grained material 1〇4 is determined by the macro 7 and the liquid's light is his intensity. It is incident on each of the calender sheets 4〇4a_C. The green light-receiving sheet 4〇4a is placed on the light-transmitting sheet 404b, and is placed in the penetrating portion. In an embodiment of the present invention, the penetrating portion U2a is disposed. Above, the blue filter 1354159 112b is placed, and the red filter 404c is placed on the penetrating portion n2c. Each of the filters 404a-c imparts a corresponding color light to the color pixels. The light imparted by the filter 404a_c determines the chrominance vaiue of the color pixel. Chroma contains color information such as a pixel's hue and saturation. 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 pixel. This luminous intensity increases the resolution under the color penetration mode. The luminous intensity is a measure of the brightness of the pixel.

In an embodiment of the invention, light 5〇2 from source 1〇2 passes through first-polarizer 120. The first polarizer 12 杈 aligns the plane of the light 5 〇 2 with a specific plane. In an embodiment of the invention, the flat surface of light 502 is aligned in a horizontal direction. Further, the second polarizer 122 has a polarization axis in the vertical direction. The penetrating portion U2a_e transmits light. In the embodiment of the invention, each of the penetrations U2a_e has an individual exchange element. Further, the parent changing element controls the intensity of light passing through each of the penetrating portions U2a_c, thereby controlling the intensity of the color light component. In addition, the light 5〇2 passes through the liquid crystal material 1〇4 after passing through the through-penetration portions 112a-c. Each of the penetrating portions 112a, i12b, and U2c has its own pixel electrode c. The potential difference between the pixel electrodes 16a-c and the common electrode 1A8 determines the directivity of the liquid crystal material 104. In an embodiment using lumps, white and blue light LK), the directivity of ^M159 followed by liquid crystal material 104 determines the intensity of light 502 incident on green light filter 504, as well as transparent spacers 5083 and 508b. • The intensity of the "light plus 2 through the green filter 504 and the transparent spacers 5〇8a and 5〇8b determines the chromaticity value of the color pixel.

This luminous intensity increases the resolution in the color-to-color penetration mode. The schematic diagram shown in the sixth diagram illustrates the role of the LCD in the color penetrating mode when the method of diffraction is used according to an embodiment of the present invention.

Alternatively, light 602 can be divided into a spectrum of colors, while different portions of the spectrum of light can pass through each of the penetrations 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 n2a, 11b, and 11c by the diffraction grating 604. The composition of the light 6〇2 passes through the first polarizer. 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 calibrated in a horizontal direction. Further, the second polarizer 122 has a polarization axis in the vertical direction. The penetrating portion a2a_c allows the components 6〇2a, c of light to be transmitted therethrough. In an embodiment of the invention, each of the penetrations U2a-c has a separate exchange element. The switching element controls the intensity of the light passing through the corresponding penetrating portion U2a_c thereby controlling the intensity of the color light component. In addition, the light component 6〇2a_c passes through the liquid crystal material just after passing through the penetrating portion 112a_e. The transmissive portions 112a, 112b, and 112e have pixel electrodes iQ6a e, respectively. The potential difference between the image and the common electrode 1 〇 8 determines the liquid crystal material properties. Then, the directivity of the liquid crystal material 104 determines the intensity of the light component 6〇2a_C of J 122 . The intensity of the center of the first component 6 passing through the second partial film 122 determines the color pixel. Further, if there is ambient light, the light reflected by the reflecting portion 11A (e.g., the third image p/f -, ώ) of the second portion 16 16 provides the luminous intensity of the color pixel. This intensity increases the resolution in color penetration mode. As in the present invention, as described in the present invention, the penetrating portions of the pixels are arranged diagonally, instead of the vertical or horizontal configuration, as is the case with the LCDs. The penetration angle, table configuration, can improve the resolution compared to the previously known LCD, because the (four) display function can be provided. In addition, there is ambient light that enhances the color image in color penetration mode.
發光強度（luminance)。所以，每—像素兼具有發光強 度與色度，這樣會增加LCD的解析度。因此，某一特定解 析度所需的像素數目會低於先前已知的LCD，藉此降低 LCf的電力消耗。另外，以電晶體邏輯(TTL)為主的介面與 先七已知的LCD所用的介面相較下，可用來降低lcd的 電肖耗。此外，因為時序控制器儲存與像素數值有關的 Λ號LCD可達到最佳化的自我更新’藉此也可降低電力 消耗。在本發明的不同實施例中，可以採用較薄的濾光片，Luminance. Therefore, each pixel has both luminous intensity 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 LCf. In addition, the transistor logic (TTL)-based interface can be used to reduce the electrical dissipation of the LCD compared to the interface used in the first seven known LCDs. In addition, because the timing controller stores an apostrophe LCD associated with pixel values, an optimized self-updating can be achieved, thereby reducing power consumption. In various embodiments of the invention, thinner filters can be used,
