全染料光刻胶透过率稳定性 All Dye photoresist transmittance stability

摘要

为了提升液晶显示器的透过率, 优化产品白平衡提升色温, 本研究在液晶显示器行业内首次使用了全染料系的蓝色光阻材料, 并搭配实际产品, 对该材料进行了一系列应用性评价。首先, 对材料进行原理性分析, 初步评估全染料系材料的透过率和光学稳定性、热稳定性; 接着, 使用该材料光谱进行初步的色度评估, 并搭载产品进行测试。测试结果表明: 此款全染料系蓝色光阻材料相较于传统颜料、染料混合系蓝色光阻材料, 透过率可提升约9%; 产品组装背光源后, 产品透过率可提升约3%, 并且可将某一款特定TV产品的色温提升至10 700 K(客户规格10 000 K±1 000 K), 对产品显示性能有较大提升。结合G8.5世代线工艺性测试和产品信赖性评价, 可以得出结论: 全染料系蓝色光阻材料具有更优异的性能, 满足量产标准, 可在G8.5世代线应用和量产。

Abstract

In order to enhance the transmittance of LCD, optimize the white balance and enhance the color temperature, this study uses All Dye Blue photoresist in LCD industry for the first time, and evaluates a series of application in actual product. Firstly, based on the rational analysis of All Dye Blue photoresist, the dye materials transmittance, optical stability and thermal stab ility are preliminarry evaluated. Then, the material spectrum is used for color simulation and it is tested by products in production line. Experimental results indicate that this All Dye Blue photoresist has the improvement of transmittance about 9% in contrast of the traditional blue which is the hybrid of pigment and dye. After assemble with the backlight, the product performance has a large improvement. The transmittance increase about 3%, and the CCT can be up to 10 700 K (customer specifications is 10 000 K+ 1 000 K) for one specific TV product. With the evaluation of line application test and reliability evaluation of G8.5 generation, it can be concluded that the All Dye Blue photoresist has more excellent performance and could meet the production standards of G8.5 generation line.
