Description

液晶显示面板及其制造方法 The liquid crystal display panel and manufacturing method

技术领域 FIELD

本发明是有关于一种液晶显示面板的制造方法,且特别是有关于一种穿透反射式液晶显示面板的制造方法. The present invention relates to a method for producing a liquid crystal display panel, and more particularly relates to a method for manufacturing a panel-transmission reflection-type liquid crystal display.

背景技术 Background technique

近年来光电相关技术不断地推陈出新,加上数字化时代的到来,进而推动了液晶显示器市场的蓬勃发展.液晶显示器具有高画质、体积小、重量轻、 In recent years, photovoltaic technologies continue to emerge, coupled with the arrival of the digital age, thus promoting the booming LCD market. The liquid crystal display has a high-quality, small size, light weight,

低驱动电压、与低消耗功率等优点,因此被广泛应用于个人数字助理(PDA)、 移动电话、摄录机、笔记本计算机、桌上型显示器、车用显示器、及投影电视等消费性通讯或电子产品,并逐渐取代阴极射线管而成为显示器的主流. Low driving voltage, and low power consumption advantages, it is widely used in personal digital assistants (PDA), mobile phones, camcorders, notebook computers, desktop monitors, automotive displays, projection televisions and other consumer communications or Electronics, substituted and gradually become the mainstream cathode ray tube display.

液晶显示器(Liquid Crystal Display, LCD)是一种利用液晶特性来达到显示效果的显示装置,由于其较传统常用的阴极射线管显示器在尺寸与重量方面有更佳的弹性,因此,液晶显示器目前常被使用在各种的个人系统上,小从移动电话、个人数字助理及数字相机上的显示屏,大到电视机及广告看板, 处处都可以见到液晶显示器的影子. The liquid crystal display (Liquid Crystal Display, LCD) is a display device using a liquid crystal display characteristics to achieve, because of its more traditional conventional cathode ray tube displays have better flexibility in terms of size and weight, and therefore, the liquid crystal display normally present are used in a variety of personal systems, small from the display on the mobile phones, personal digital assistants and digital cameras, televisions and large billboards, everywhere can see the shadow of a liquid crystal display.

一般的穿透式(transmissive)显示器在室外及强光下,影像会被褪掉而导致对比P争低,相较之下,反射式(reflective)显示器乃是依赖外来光源来达到显示效果,因此在户外及强光下反而会呈现出更佳的效果及对比,且可减少消耗大量功率的背光使用时机,所以非常适合用于可携式产品上.不过,反射式显示器较难在高分辨率下达到高对比及高彩色品质的影像,尤其是全彩化的要求.但是当环境光源不足时,反射式显示器的对比与亮度大受折扣, 因此若能配合辅助背光源的穿透式技术来制作半反射半穿透(transflective)显示器,其可同时具有穿透式与反射式的优点,适用于非晶硅的薄膜晶体管(a-Si TFT)或低温多晶硅的薄膜晶体管(low temperature polysilicon TFT)等主动驱动技术,因此目前低耗电TA信息产品大都采用这类的半反射半穿透显示面;f反面板. General transmissive (Transmissive) display and the outdoor light, the image contrast is caused by P contention faded low contrast, reflective (Reflective) displays but rely on external sources to achieve the display, so instead, in outdoor and bright light will show a better effect and contrast, and can reduce backlight power consumption of a large amount of time to use, it is very suitable for the portable product. However, reflective displays is more difficult in high resolution under achieve high contrast and high color quality images, particularly full-color requirements. However, when there is insufficient ambient light, contrast and brightness of the reflective display greatly discount, so if the auxiliary backlight technology with transmissive to production of semi-reflective semi-transmission (a transflective) display, which may have a transmissive and reflective advantages simultaneously for amorphous silicon thin film transistor (a-Si TFT) or low-temperature polysilicon thin-film transistor (low temperature polysilicon TFT) other active driving technology, low power consumption and therefore the TA information currently most products using such semi-reflective transflective display surface; F anti panel.

半反射半穿透显示面板可利用背光系统辅助环境光源的不足.当环境光源充足时,半反射半穿透显示面板不需用到内建光源,而是充分利用环境光源并可省略掉背光源,以达成省电的效果.但是,当穿透区域与反射区域液 Semi-reflective transflective display panel may lack an auxiliary ambient light source using the backlight system when adequate ambient light, semi-reflective transflective display panel does not need to use the built-in light sources, but take advantage of ambient light and backlight omitted , to achieve power saving effect. However, when the penetration region and the reflective region of the liquid

晶盒间隙(Cell gap)相同时,穿透区域的穿透率-电压曲线(transmittance v. voltage curve)与反射区域的反射率-电压曲线(reflectance v. voltage curve)并不一致. Crystal cell gap (Cell gap) phase while penetration transmittance region - voltage curve and the reflectivity of the reflective region (transmittance v voltage curve.) - voltage curve (. Reflectance v voltage curve) is not consistent.

传统的半穿透半反射液晶显示器(Transflective display),若使用单液晶盒间隙(Single cell gap),则穿透区和反射区使用不同的控制电路,或是穿透区域和反射区域使用不同的晶体管进行控制,可能增加阵列(Array)的复杂性和困难度,驱动方式也较复杂. Conventional transflective liquid crystal display (Transflective display), when the single cell gap (Single cell gap), the transmissive region and the reflective areas using different control circuits, and penetrate and reflective areas using different a control transistor, the complexity and difficulty, drive arrays may be increased (the array) is also more complex.

美国专利第6812978号则公开一种半反射半穿透显示面板技术,主要是将液晶胞设计成为双液晶盒间隙(Dual cell gap),或是外贴半反射半穿透膜. 图1示出传统双液晶盒间隙液晶显示单元的剖面示意图,如图l所示, 一半反射半穿透显示面板1包括有一对平行设置的上基板10与下基板20,以及一液晶层30填入上基板10与下基板20的空隙内.在上M 10的内表面上, 也就是面对下基板20的表面上,包括有一黑色矩阵层12及一共享电极层14, 黑色矩阵层内嵌设彩色滤光层(未示出),在共享电极14的表面上具有一上配向层16.在下基板20的内表面上,也就是面对上基板IO的表面上,是由多条垂直相交的栅极线与数据线以构成矩阵排列的象素区域. U.S. Patent No. 6,812,978 discloses a semi-reflective transflective display panel technology, the liquid crystal cell is primarily designed dual cell gap (Dual cell gap), or affixed to the outer semi-reflective semi-permeable membrane. Figure 1 shows a conventional dual cell gap of the liquid crystal display unit is a schematic cross-sectional view shown in FIG. L, half reflective transflective display panel 1 comprises a pair of upper substrate 10 disposed in parallel 20 and the substrate 10 is filled a liquid crystal layer 30 on the lower substrate and the lower substrate 20 is a void in the inner surface of the upper M 10, which is facing the upper surface of the lower substrate 20 includes a black matrix layer 12 and a common electrode layer 14, a black matrix layer, a color filter disposed inline layer (not shown), having a plurality of gate lines perpendicular to an upper alignment layer 16 on the inner surface of the lower substrate 20, i.e. on the surface facing the upper substrate of IO, in the upper surface of the common electrode 14 pixel region and the data lines arranged in a matrix configuration.

每一个象素区域由一薄膜晶体管TFT (未示出)来控制,并至少间隔成穿透区域40和反射区域50.象素区域包括透明电极层22位于下基板20之上, 一保护层24位于透明电极层22之上.在反射区50的4呆护层24之上具有一反射电极26,而一下配向层28位于保护层24及反射电极26之上.液晶层30设置于上配向层16与下配向层28之间. Each pixel region is controlled by a thin film transistor TFT (not shown), and spaced at least over 20 to penetrate the reflection region 50. The region 40 and the pixel region includes a transparent electrode layer 22 located on the lower substrate, a protective layer 24 on the transparent electrode layer 22 having a reflective electrode 26 on protective layer 4 stay 24 of the reflective area 50, and at 24 with the protective layer located over the electrode 26 and the reflective layer 28 to the liquid crystal layer 30 is disposed on the alignment layer 16 and between the lower alignment layer 28.

由于图1中可知,在一个象素区域内.液晶层30中会形成两种厚度区域,其中液晶盒间隙dl形成于反射电极层26上方,也就是位于反射区域50 内,液晶盒间隙d2形成于透明电极层22上方,也就是位于穿透区域40内, 而且d2约为dl的两倍.因此,当入射光线穿越液晶层30时并禎反射区域50的反射电极26反射后,其走过的光径会和背光经过穿透区域40的光径相同,因而可以使得穿透区域40的穿透率-电压曲线(transmittance v. voltage curve)与反射区域50的反射率-电压曲线(reflectance v. voltage curve)达到一致。 Since seen in FIG. 1, in a pixel region. The liquid crystal layer 30 will form two thickness regions, wherein the liquid crystal cell gap dl is formed above the reflective electrode layer 26, which is located in the reflection region 50, the liquid crystal cell gap d2 is formed above the transparent electrode layer 22, which is located within the penetration region 40, and d2 is about twice dl. Thus, when the incident light and the reflective electrode 26 through the liquid crystal layer 30 when the reflective area 50 after reflecting Zhen, through which and a backlight will light path through the penetration region of the same optical path 40, so that the penetration region may thus transmittance of 40 - (. transmittance v voltage curve) the reflectivity curve of the voltage and the reflective area 50 - voltage curve (reflectance v . voltage curve) to reach consensus. 然而,要将液晶胞设计成为双液晶盒间隙,会遭遇到制作工艺复杂且不易控制的问题,而若仅借由外贴半反射半穿透膜仍无法达到理想的显像效果。 However, to the liquid crystal cell designed dual cell gap, encounter manufacturing process complicated and difficult to control the problem, but only if attached by means of an outer semi-reflective semi-permeable membrane is still not achieve the desired imaging effect. 有鉴于此,如何在具有单一液晶盒间隙的液晶胞设计的前提下,达到穿透区域与反射区域所需的光学设计,将是半反射半穿透显示面板技术的重要课题. In view of this, under the premise of how a liquid crystal having a cell gap of a single cell design, required to achieve penetration region and the reflective region of the optical design, the semi-reflective transflective display panel technology important issue.
