Do you know LCD LCD screen? Today for the specific analysis of everyone, I hope to help you. TN Reflective LCD Screen semi-reflective LCD abbreviated TR-LCD, it is a word for transmission and reflection synthesis. TR-LCD structure, because the reflected light passes through the liquid crystal layer twice, the light path of the reflected light is twice different from that of the transmitted light region. TR-LCD disadvantage is that when the surrounding environment light is not too dark, turn on the backlight, and see the image of the transmission region and the reflection region at the same time, which reduces the brightness of the picture quality. In addition, in the reflection region, the light passes through the color film layer twice, and the image of the reflection region and transmission region has color deviation. the fabrication process of different thickness reflection zone and transmission zone in the liquid crystal box is more complicated, and the driving characteristics of transmission region and reflection region are different, which brings many difficulties in practical fabrication and application. LCD classification can be divided into five main types according to display technology, such as OLED、TFT-LCD、TFD-LCD、SIN-LCD、GF-LCD. The technology LCD backlight can also be divided into reflective LCD and transmission LCD.. The transmission type LCD display depends on the backlight source and consumes a lot of electricity, but the reflection type LCD does not need the backlight source, it is dependent on the environment light display, the power consumption is low, suitable for mobile phone, PDA and other portable electronic products, so the reflection type LCD has been studied for a long time. The early antireflective LCD used 90°TN mode, using two polarizers, and later proposed a reflective mixed mode using one polarizer TN、 reflective VA and other modes. a disadvantage of reflective LCD is that the ambient light is reflected on the panel, and the contrast is only 5:1-30:1. Because reflex LCD mainly used in e-books and other production products, so it is required to achieve the reflectivity of the general paper, that is ,70-90%.
