本发明是关于一种显示面板结构，尤指一种广色域显示面板结构。The invention relates to a display panel structure, in particular to a wide color gamut display panel structure.
背景技术Background technique
随着科技的发展和人们对于显示产品色彩效果的与日俱增的要求，液晶显示面板也朝着提升色域(color gamut)的方向发展，亦即增加使人眼所能识别出的颜色，色域愈广代表的是人眼可辨识的颜色覆盖率愈高，因此广色域也成为显示面板显示质量的一种指标。With the development of technology and people's increasing requirements for the color effect of display products, LCD panels are also developing in the direction of increasing the color gamut (color gamut), that is, increasing the colors that can be recognized by the human eye, and the color gamut is getting stronger. Wider means that the higher the coverage of colors that can be recognized by the human eye, so the wider color gamut has also become an indicator of the display quality of the display panel.
现有技术中用以提升面板色域的方法是利用背光膜材中内含的量子点膜材(quantum dot film)，以蓝光LED激发量子点膜材产生窄带宽的激发光源，而形成广色域的光学表现。然而，由于一般量子点膜材含镉(Cd)，具有毒性，会对环境造成伤害，因此如何在广色域的显示技术需求与无毒环保的世界潮流间取得平衡，甚至双赢，是业界仍在努力的目标之一。The method used in the prior art to improve the color gamut of the panel is to use the quantum dot film contained in the backlight film to excite the quantum dot film with a blue LED to generate an excitation light source with a narrow bandwidth to form a wide-color The optical performance of the field. However, because the general quantum dot film material contains cadmium (Cd), which is toxic and will cause harm to the environment, how to achieve a balance between the demand for wide-color gamut display technology and the world trend of non-toxic and environmentally friendly, or even a win-win situation, is still an issue in the industry. One of the goals of the effort.

如图5所示，金属线栅偏光板是将金属线配置于一透明基板上做成，金属线平行相间排列成光栅，金属线中的电子只能沿导线运动，当光照射在金属线栅偏光板上时，光波电向量在金属线方向的振动会被金属线中的电子吸收，垂直金属线方向的光波电向量就能通过，这样只有沿导线纵向的光子被吸收，而横向的光子未被吸收，从而达到偏振效果。除了以金属线做成平行相间排列的光栅之外，亦可用光学蚀刻的方法，在沉积有金属薄膜的基底上蚀刻出所需宽度的导线，在一实施例中，也可以以纳米压印的方式形成金属线。在本实施例中的金属线栅偏光板的金属线51的间距G为纳米等级(10-200nm)。其高度H为50-1000nm。使用的金属可为铝、银、金、铅、铜等，尤以铝为佳；透明基板50的材料可为玻璃，在一实施例中，金属线可形成于薄膜晶体管基板之上。As shown in Figure 5, the metal wire grid polarizer is made by disposing metal wires on a transparent substrate.

On the polarizer, the vibration of the light wave and electric vector in the direction of the metal wire will be absorbed by the electrons in the metal wire, and the light wave and electric vector in the direction perpendicular to the metal wire can pass through, so that only the photons along the longitudinal direction of the wire are absorbed, while the horizontal photons are not. is absorbed to achieve the polarization effect. In addition to using metal wires to make gratings arranged in parallel and alternately, optical etching can also be used to etch wires of required width on the substrate deposited with metal films.

For example, the phase difference value LC Delta_nd of the liquid crystal is designed in the range of 300-370 nm, so that the phase difference value R0 of the x and y planes is 50 ~100nm, preferably 70-100nm, and the x, y, z stereo phase difference Rth is between 200-350nm, preferably 270-320nm. Wherein, R0=(nx-ny)×d; and Rth=((nx+ny)/2-nz)×d, wherein nx, ny and nz respectively represent the compensation film 21 on the x-axis, y-axis and z-axis The three-dimensional spatial refraction index, d represents the thickness of the compensation film 21 . At this time, it can have a viewing angle performance equivalent to or better than that of the original panel double-sided compensation film.
