Description

像素单元技术领域本发明是关于一种像素单元及其控制系统,特别是关于一种可改善色饱和度及亮度的像素单元。 TECHNICAL FIELD The present pixel invention relates to a pixel cell and its control system, in particular on an improved color saturation and brightness of the pixel unit. 背景技术液晶面板主要包括一基板、 一彩色滤光板与两者之间的液晶层。 BACKGROUND ART The liquid crystal panel includes a liquid crystal layer between the substrates, and a color filter both. 其中基板上具有数组型式的多个薄膜晶体管及一控制电路,主要用以控制图样或文字的显示。 Wherein the thin film transistor array having a plurality of types, and a control circuit board for controlling the main display text or pattern. 彩色滤光板主要提供红、蓝、绿三颜色的配色。 Providing primary color filter of red, blue and green colors of the color. 但因液晶面板本身并不发光,因此需要一外加面光源以提供均匀、高亮度、广视角的显示效果。 But the liquid crystal panel itself does not emit light, it is necessary to provide a surface light source uniformly applied, high brightness, wide viewing angle display. 一般依显示器的种类,面光源又可分为背光模块与前光模块,其中背光模块位于液晶面板后面,主要用于穿透式显示器,前光模块位于液晶面板前面,主要用于反射式与半反射式显示器。 Generally depending on the kind of display, a surface light source of the backlight module can be divided into the front light module, wherein the module is located behind the liquid crystal panel backlight, transmissive display is mainly used, the optical module is located in front of the front liquid crystal panel, it is mainly used for the semi-reflective reflective display. 无论是反射式或穿透式的液晶显示器,当彩色滤光板的吸收率过大或颜色浓度提高时,穿透率就会大幅降低。 Either reflective or transmissive liquid crystal display, when the absorptance of the color filter is too large or improve the color density, the transmittance will be significantly reduced. 因此显示器的亮度受到极大的限制, 在设计高亮度显示器时必须考虑此一限制。 Thus the brightness of the display is greatly restricted, this restriction must be considered when designing a high brightness display. 请参照图1A,为公知液晶面板的像素单元配置方式。 Referring to Figure 1A, the pixel unit is a well-known arrangement of the liquid crystal panel. 传统的液晶面板IO 具有一下基板11及一上基板12,并包含了多个像素单元(pixel) 13,每个像素单元13只包含一红色子像素(sub-pixel) 131、 一绿色子像素132及一蓝色子像素133。 IO conventional liquid crystal panel having a lower substrate 11 and upper substrate 12, and includes a plurality of pixel units (pixel) 13, each pixel unit 13 comprises a red sub-pixel (sub-pixel) 131, a green subpixel 132 133, and a blue subpixel. 每个子像素均为一立体结构,以红色子像素131为例,其结构包含一光致抗蚀剂层121形成于上基板12的下表面、 一薄膜晶体管111及一像素电极112位于下基板11的上表面,以及位于光致抗蚀剂层121与像素电极112之间的液晶层14。 Each sub-pixel are a three-dimensional structure, to the red sub-pixel 131, for example, a structure comprising a photoresist layer 121 formed on the lower surface of the upper substrate 12, a thin film transistor 111 and a pixel electrode 112 located on the lower substrate 11 the upper surface, and a liquid crystal layer 14 is located between the photo-112121 and the pixel electrode resist layer. 近来,为了提升液晶面板10亮度而在每个像素单元13中增加了其它颜色的子像素,例如白色子像素。 Recently, in order to enhance the luminance of the liquid crystal panel 10 to increase the sub-pixels of other colors in each pixel unit 13, for example white sub-pixel. 由于液晶面板10的背光源(未图标)通常为白光,因此只要在上基板12上另增加一透明区即可使每个像素单元均包含红、 绿、蓝、白四种子像素。 Since the backlight (not shown) of the liquid crystal panel 10 is normally white, so long as the increase in the other transparent substrate 12 a region to each pixel cell contains red, green, blue, white four sub pixels. 具体的作法如图1B-图1C所示,以一透明光致抗独剂层l24搭配红绿蓝三种光致抗蚀剂层121, 122, 123而改善像素单元的亮度。 FIG concrete way 1B- 1C, to separate a transparent light-resist layer with red, green and blue l24 photoresist layer 121, 122, 123 improve the brightness of the pixel unit. 图1B为条状(stripe)配置;图1C为马赛克状(mosaic)配置。 FIG 1B is a stripe configuration (stripe); FIG. 1C is a mosaic-like configuration (mosaic). 假设材质本身的穿透率为100%,但由于光致抗蚀剂层121, 122, 123本身含有色彩,只能容许该色彩的光波通过。 Transmittance of the material itself is assumed to be 100%, but the photoresist layer 121, 122, 123 itself contains color, allowing only the light through the color. 对三原色子像素131, 132, 133 其中之一来说,只能容许三种色光的其中一种通过而仅剩下三分之一的亮度。 Three primary sub-pixels 131, 132, 133 of which one, the only one of the three color lights allowed by leaving only one third of the brightness. 以一个含有三原色子像素131, 132, 133的像素单元13来说,每个子像素131, 132, 133的透光面积占像素单元13透光面积的三分之一,因此一个像素单元13的总透光量为3x1/3x1/3=1/3。 In the sub-pixels of three primary colors containing a 131, a pixel unit 132, 133, 13, each sub-pixel 131, light transmissive area 132, 133 is one third of a pixel area of ​​the light transmitting unit 13, and thus a total pixel unit 13 an amount of light transmitting 3x1 / 3x1 / 3 = 1/3. 在上基板12加入透明光致抗蚀剂层124 后, 一个像素单元13含有四个子像素,每个子像素的透光面积占像素单元11 透光面积的四分之一,若透明光致抗蚀剂层124的光穿透率为100%,则此种像素单元的总透光量为3 x 1/3 x 1/4+1 x 1/4=1/2 〉 1/3。 After the addition of the transparent substrate 12 on photoresist layer 124, a pixel unit 13 comprises four sub-pixels, each sub-pixel area of ​​the light-transmitting a quarter of the light-transmitting area of ​​the pixel unit 11, if the transparent photoresist a light transmittance layer 124 is 100%, the total light transmittance of this pixel unit in an amount of 3 x 1/3 x 1/4 + 1 x 1/4 = 1/2> 1/3. 如此,改变上基板12上的像素配置,将三原色光致抗蚀剂层121, 122, 123 (RGB)改为三原色光致抗蚀剂层121, 122, 123加上一透明光致抗蚀剂层124(RGB+W)。 Thus, changing the pixel arranged on the upper substrate 12, the three primary colors of the photoresist layer 121, 122, 123 (the RGB) primary colors to the photoresist layer 121, 122, 123 together with a transparent photoresist layer 124 (RGB + W). 利用透明区124增加透光量,使得使所有颜色变亮。 A transparent region 124 to increase the amount of light transmissive, so that all color brighter. 虽然如此,加入白光混色却使得画面偏白,也造成色彩々包和度下降。 Nevertheless, it was added so that the picture white whitish color mixing, color 々 packet and also causes decreased. 由以上叙述可知,液晶显示器的亮度受限于光致抗蚀剂层的光穿透率。 From the above description, the liquid crystal display is limited by the brightness of the light transmittance of the photoresist layer. 若要增加透光量,则需要增加白色子像素而改变像素(pixel)的配置。 To increase the amount of light transmission, we need to increase the white sub-pixel to change the configuration of pixels (pixel) of. 但公知技术无法有效控制白色子像素的透光量,致使增加该部分的透光量后,影响了三原色子像素的色饱和度。 However, the known techniques can not effectively control the amount of light passing white sub-pixel, resulting in increasing the amount of the light-transmitting part, it affects color saturation of the primary colors of sub-pixels. 本发明改变显示器的像素结构,同时配合电路控制而提高了显示器的色饱和度及亮度。 The present invention changes the pixel structure of the display, in conjunction with the control circuit to improve color saturation and brightness of the display. 发明内容本发明的目的在于提供一种像素单元,对固有的红绿蓝三色子像素作光补偿,并提供一控制系统计算出最佳的控制信号组合,输入像素单元的每个子像素以产生最好的混色效果。 Object of the present invention is to provide a pixel unit, the inherent sub-pixels for red, green and blue light compensation, and providing a control system calculates the best combination of control signals, each sub-pixel of the input pixel unit to generate the best blending effect. 本发明的显示面板的像素单元,包括三个子像素,每个子像素皆可分为一第一光穿透区及一第二光穿透区,该第一光穿透区之内设有一第一晶体管及一第一光致抗蚀剂层,该第二光穿透区之内设有一第二晶体管及一第二光致抗蚀剂层。 Pixel cell display panel of the present invention includes three sub-pixels, each sub-pixel Jieke light-transmissive region is divided into a first and a second light-transmissive region, which consists of the first light-transmissive region has a first a first transistor and a photoresist layer, the light-transmissive region of the second site a second transistor and a second photoresist layer. 该第一光致抗蚀剂层与该第二光致抗蚀剂层是形成于一滤光板上,并具有不同的厚度或面积。 The first photoresist layer and the second photoresist layer is formed on a filter plate, and having a different thickness or area. 上述第一晶体管与第二晶体管所接收到的数据信号具有一函数关系,通过该两数据信号搭配该两不同厚度或面积的光致抗蚀剂层,使每个子像素皆可产生新的灰阶亮度及增加可显示的颜色数目。 The first transistor and the second transistor to the received data signal having a functional relationship, with the photoresist layer or two areas of different thickness by the two data signal, each sub-pixel gray scale to generate new Jieke increasing the brightness and the number of colors that can be

the pixel signal control unit. 控制系统主要包括一反多任务器(de-multiplexer)及一多任务器(multiplexer)。 The control system includes an anti-multiplexer (de-multiplexer) and a multiplexer (multiplexer). 反多任务器于接受一控制信号后,对该控制信号进行一函数运算以分离出一第一信号,再将该控制信号及该第一信号输出至多任务器。 Inverse multiplexer after receiving a control signal, the control signal is a function of the operation to separate a first signal, then the control signal and the first control signal to the multiplexer output. 多任务器接受反多任务器输出的控制信号及第一信号之后,对该控制信号进行一算法以转换为一第二信号,再将该第一信号输出至该第一晶体管,该第二信号输出至该第二晶体管。 After the multiplexer receives a control signal and a first signal output from the inverse multiplexer, the control signal algorithm to be converted into a signal of a second, then the first signal to the first transistor, the second signal output to the second transistor. 由第一光穿透区及第二光穿透区所组成的像素单元结构,再加上控制系统的电路控制机制,使得平面显示器亮度上升,色彩饱和度提高。 Pixel unit structure by the first light penetrating the light transmissive region and a second region composed, together with the control mechanisms control system circuit, such that the planar display brightness increased, improving color saturation.
