Abstract

Trans-flective liquid crystal display (TRLCD) and pixel structure of the same, wherein the TRLCD concludes a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a color gamut adjuster sub-pixel. The color gamut adjuster sub-pixel, the red sub-pixel, the green sub-pixel, and the blue sub-pixel are disposed in array. The color gamut of the color gamut adjuster sub-pixel is less than that of any of the red sub-pixel, the green sub-pixel, and the blue sub-pixel. A reflective region area of the color gamut adjuster sub-pixel is greater than that of any of the red sub-pixel, the green sub-pixel, and the blue sub-pixel. Because a sub-pixel that can reduce the color gamut is designed in the pixel structure, it can adjust the transmittance of the TRLCD and the color saturation of the whole pixel.

Description of the invention (1) The technical field to which the invention belongs and its day-to-day junction penetration and reflection semi-transmission reflection The previous technology combined in recent years, and the corresponding LCD has become a non-spontaneous panel. The transflective type does not matter whether the surrounding backlight is bright, so it must be found in Yanfeng Assistant. In recent years, various parties have set their sights to reverse the liquid crystal display layer reflective plate. The present invention relates to a transflective type The liquid crystal display has a trans-flective liquid crystal display (referred to as TRLCD) structure (pixel structure), and in particular, it relates to a type of liquid crystal display with similar color saturation (color saturation) of a part and its daylight structure. As the junction with electronic components becomes more complete, however, it is complicated. There are three types of transmissive liquid crystal display liquid crystal displays because the liquid crystal display provides an external light source. The module is used as a light source, so it must be used in LCD displays. The backlight module consumes a lot of power such as personal digital and other portable products. Crystal displays have gradually been experiencing problems with power consumption. The function of a source is plated on the lower substrate of a column-type (STN) reflective plate. When external light comes, the development of liquid crystal displays is more widely used, and the functions of display elements are also becoming more and more bright. Therefore, Requires a brightness, depending on the light source, the reflective LCD and reflective LCD need to rely on the backlight to be bright or not. Use the transmissive type to achieve the display function. However, mobile phones, personal digital assistants (P, PDA), and E-Book seeks new power-saving technology to solve the problem of using reflective liquids from external light sources, which can greatly improve the nematic (TN) or super twist direction of liquid crystal displays. It is mainly on the liquid crystal surface. The reflecting plate has the ability to reflect external light

Description of the invention (2) When the line is sufficient, its display quality is good. It can be seen that the reflective liquid crystal display does not require a backlight module to achieve the display purpose, and its power consumption is greatly reduced. However, if an appropriate light source is not provided, such as a front light source (f r ο n t 1 i g h t), the reflective liquid crystal display cannot be used in a weak environment. Therefore, a type of liquid crystal display called a "transflective liquid crystal display" is currently attracting attention. Its structure is the same as that of a transmissive liquid crystal display, which has two glass substrates, a liquid crystal layer located between the substrates, and a color filter film. (Co 1 or fi 1 ter, abbreviated as CF); the difference is that the daylight electrode of the transflective reflective liquid crystal display has a transmissive area and a reflective area. The transmissive area is usually a transparent electrode and the reflective area is a metal electrode. Taking a pixel structure of a transflective liquid crystal display as an example, it will be shown in Figs. 1A and 1B. Please refer to FIG. 1A and FIG. 1B. The structure of a conventional transflective liquid crystal display 1 0 0 a is a red (R) filter film 1 0 2 a located between a liquid crystal layer and a glass substrate. The green (G) filter film 1 0 2 b and the blue (B) filter film 1 0 2 c, and the portion 104 indicated therein are the transmissive portions of the transflective liquid crystal display. The structure 1 0 0 b is a day element electrode 106 located between the liquid crystal layer and another glass substrate. The penetrating region 1 0 6 b corresponds to the position of the position 104 in FIG. 1 A and reflects. The area 1 0 6 a is a part other than the penetration area 10 6 b. When the upper and lower structures Γ〇 0 a and 1 0 0 b are combined, it is a pixel structure. However, the conventional transflective liquid crystal display often has a problem that the color saturation of the reflective area and the transmissive area is too large. This is because the light emitted from the reflective area needs to pass through the color filter film (CF) twice. By penetration

11946twf.ptd 第7頁 1228622 五、發明說明（3) 區域射出的光線只經過一次彩色濾光薄膜，因此反射區域在色彩飽和度上明顯優於穿透區域。因此，最新的改良方式有以下兩種··一種是對紅色（R )濾光薄膜1 0 2 a、綠色（G ) 濾光薄膜1 0 2 b、藍色（B )濾光薄膜1 0 2 c中對應於穿透區域 106b的部位104之材質或厚度（請參考第1A圖與第1B圖）作改變，也就是稱為π雙重彩色濾光薄膜（Dual CF)n的方法，以達到增加穿透區域之色彩飽和度的目的；另一種是稱為’’於彩色濾光薄膜中有開口（ Η ο 1 e I n C F )π的方法，顧名思義就是在彩色濾、光薄膜中開洞，如第2圖所示，在半穿透反射式液晶顯示器的上晝素結構2 0 0 a之紅色（R ) 濾光薄膜2 0 2 a、綠色（G)濾光薄膜2 0 2 b、藍色（B)濾光薄膜2 0 2 c 中對應於反射區域的部位2 0 4開洞，以達到降低反射區域之色彩飽和度的目的。然而，前述改良方法均有其缺點，亦即採用”雙重彩色濾光薄膜’’的方法時，需用到六道光罩，故其製程繁複且易出錯，而且這個方法常用較昂貴的材料作為對應於穿透區域1 0 6 b之部位1 0 4的彩色濾光薄膜的材質，因此其至造成本也較一般貴，此外彩色濾光薄膜在材質選用與厚度調整上,十分耗時；而用π於彩色濾光薄膜中有開口 ”的方法時，則會因為彩色濾光薄膜（C F )有最小蝕刻半徑的限制，所以無法完全符合模擬，故在某些情形下無法採行此種方法。發明内容因此，本發明之目的是提供一種半穿透反射式液晶顯11946twf.ptd Page 7 1228622 V. Description of the invention (3) The light emitted from the area passes through the color filter film only once, so the reflection area is significantly better in color saturation than the transmission area. Therefore, the latest improvements include the following two types. One is the red (R) filter film 1 0 2 a, the green (G) filter film 1 0 2 b, and the blue (B) filter film 1 0 2 The material or thickness of the part 104 corresponding to the penetrating region 106b in c (please refer to FIG. 1A and FIG. 1B) is changed, which is a method called π dual color filter film (Dual CF) n to increase The purpose of the color saturation of the penetrating area; the other is a method called `` opening in the color filter film (Η ο 1 e I n CF) π, as the name suggests is to open holes in the color filter and light film, As shown in FIG. 2, the red (R) filter film 2 0 2 a, the green (G) filter film 2 0 2 b, and the blue color The color (B) portion of the filter film 2 0 2 c corresponding to the reflection area 204 is opened to reduce the color saturation of the reflection area. However, the aforementioned improved methods all have their disadvantages. That is, when using the "dual color filter film" method, six photomasks are required, so the process is complicated and error-prone, and this method often uses more expensive materials as the corresponding method. The material of the color filter film at the position 104 of the penetrating region 1 0 6 b is more expensive than normal. In addition, the color filter film is very time-consuming in terms of material selection and thickness adjustment; When the method of “π has an opening in the color filter film”, because the color filter film (CF) has a limitation of the minimum etching radius, it cannot fully meet the simulation, so this method cannot be adopted in some cases. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a transflective liquid crystal display.

Description of the invention (15) The color filter film is integrated in the thin film transistor liquid crystal display (CO A) on the thin film transistor array (CO A). Therefore, one of the features of the present invention is to adopt a pixel structure including red, green, blue, and chroma adjustment subdivisions, and the chroma of the chroma adjustment subdivisions is less than the chroma of other subdivisions and The area of the reflection area of the chroma adjustment sub-pixel is larger than the area of the reflection area of any of the other sub-day pixels. Therefore, the present invention can reduce the difference in color saturation between the reflection area and the penetration area by increasing the ratio of the reflection area of the light-colored subdivision and reducing the chroma of the reflection area of the color subdivision. In addition, one of the features of the present invention is that it does not need to be known. The method of Dual CFn requires six masks, uses expensive materials, and consumes a lot of time in material selection and thickness adjustment, so it can not only simplify the process, but also reduce Cost. Furthermore, because the present invention is not limited by the etching radius, it can fully meet the simulation of various situations. Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention. Anyone skilled in this art Various changes and modifications can be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the attached patent application.
