Description

液晶显示面板及液晶显示装置Liquid crystal display panel and liquid crystal display device 技术领域Technical field
本发明涉及显示技术领域，尤其涉及一种液晶显示面板及液晶显示装置。The present invention relates to the field of display technology, in particular to a liquid crystal display panel and a liquid crystal display device.
背景技术Background technique
液晶显示器（Liquid Crystal Display，LCD）具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。如：液晶电视、移动电话、个人数字助理（PDA）、数字相机、计算机屏幕或笔记本电脑屏幕等，在平板显示领域中占主导地位。Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen, etc., occupy a dominant position in the field of flat panel display.
随着液晶显示技术的发展，高穿透率、大视角成为液晶显示装置发展的趋势，如何改善穿透率和视角成为未来发展的重要方向之一。聚合物稳定垂直对齐 (Polymer stabilized vertical alignment，PSVA)型液晶显示面板开始得到广泛应用，PSVA型液晶显示面板使用负性液晶材料，液晶分子长轴加电时倾向于垂直电场方向排列。在未施加电压时液晶分子长轴垂直于基板表面，施加电压会使液晶分子向平行基板方向倾倒。为了拓宽视角，一个亚像素被划分成多个区域，加电时使液晶分子朝不同方向倾倒，从而使不同的方向观察的效果趋于一致。With the development of liquid crystal display technology, high transmittance and large viewing angle have become the development trend of liquid crystal display devices, and how to improve the transmittance and viewing angle has become one of the important directions of future development. Polymer stable vertical alignment (Polymer stabilized vertical alignment, PSVA) type liquid crystal display panels have begun to be widely used. PSVA type liquid crystal display panels use negative liquid crystal materials, and the long axis of the liquid crystal molecules tend to be aligned in the vertical electric field direction when the long axis is energized. When no voltage is applied, the long axis of the liquid crystal molecules is perpendicular to the surface of the substrate, and the application of voltage causes the liquid crystal molecules to tilt toward the direction parallel to the substrate. In order to widen the viewing angle, a sub-pixel is divided into multiple areas, and the liquid crystal molecules are tilted in different directions when power is applied, so that the effects of viewing from different directions tend to be consistent.
PSVA显示模式具有高对比度，超低暗态效果等优点。但PSVA显示模式在大视角伽马（gamma）曲线会发生偏离，即产生色偏，会影响观看效果。为了降低大视角色偏，拓宽视角，会通过电路设计，将子像素（pixel）分为主区（main-pixel）和次区（sub-pixel），从而使子像素内形成8畴（domain）设计，即畴数量增加，使得一个子像素在显示时具有两种的不同伽马曲线，在大视角时产生的伽马曲线偏离会减小，从而提高视角，降低大视角色偏。但是，更改电路设计会增加栅极线（Gate）或者数据线（Date）及薄膜晶体管（Thin Film Transistor，TFT）数量，导致开口率减小，增加驱动难度。而且次区经过分压后有效电压降低，从而使穿透率有很大的降低。为了解决视角及色差问题，我们研究发现影响视角的最大因子是蓝色子像素的伽马曲线的偏移。PSVA display mode has the advantages of high contrast, ultra-low dark state effect and so on. However, the PSVA display mode will deviate from the gamma curve at a large viewing angle, that is, color shift will occur, which will affect the viewing effect. In order to reduce the large-view role deviation and widen the viewing angle, the sub-pixel (pixel) will be divided into main-pixel and sub-pixel through circuit design, so that 8 domains (domain) are formed in the sub-pixel The design, that is, the increase in the number of domains allows a sub-pixel to have two different gamma curves during display, and the deviation of the gamma curve generated at a large viewing angle will be reduced, thereby increasing the viewing angle and reducing the large viewing angle deviation. However, changing the circuit design will increase the gate line (Gate) or data line (Date) and thin film transistor (Thin Film Transistor, TFT) number, resulting in a reduction in aperture ratio, increasing the difficulty of driving. Moreover, the effective voltage of the sub-region is reduced after the voltage is divided, so that the penetration rate is greatly reduced. In order to solve the problem of viewing angle and chromatic aberration, we found that the biggest factor affecting the viewing angle is the shift of the gamma curve of the blue sub-pixel.
