dc.description.abstract | In the design stage of the panel factory, the first priority is often the transmittance rate. Often when the transmittance rate is required, certain conditions are sacrificed, or the cost is increased to meet the requirements. Therefore, the design unit often needs to solve the dilemma in this respect. If it is simply to change the design slightly and match it with the theory, there is a chance to meet this requirement.
Under the basic structure of the panel, the brightness of the light will be decadence when the backlight penetrates through different cell layers. Therefore, in the traditional design, the color filter is matched with different types of color groups and film thickness; or the backlight is replaced with a different type LED types, but these are sacrifices of red, green, blue, and white color point shifts or some cost additions to achieve increased transmittance. But it should be possible to improve the internal design of the panel to increase the transmittance rate.
Therefore, we specially studied Pixel design, 1Dot 1 Domain, 1Dot 2 Domain, 2Dot 2 Domain Each has its own advantages and disadvantages; ITO (Indium Tin Oxide) on the TFT thin-film transistor side is designed with different widths, and the alignment film with different angles and BM widths are designed for transmittance Research on the improvement of the overall high transmittance rate optimization effect.
And use Taguchi method to analyze, confirm what kind of matching conditions will increase the transmittance rate, and output the product, and confirm whether the effect is so through actual measurement.
Under the condition of using negative liquid crystal, the width of ITO (Indium Tin Oxide) is reduced to 2.5μm in the Pixel transmittance area under 16μm, 3 ITO is used, the BM width is 5μm, and the alignment angle is 0 degrees. Below, the transmittance rate is indeed 5.6%, and the contrast is about 1800. Compared with other poor conditions, the penetration rate can be improved by 30%. | en_US |
