Compared to the original method used to set the touch panel on the liquid crystal panel, the study of the integration of the touch panel function with the LCD panel has become increasingly prevailing. The integration of touch panels and LCD panels includes the "In-Cell" method and "On-Cell" method. In-cell refers to the method of embed the function of the touch panel into the LCD pixel. ON-CELL refers to the way to embed the function of the touch panel into the color filter substrate substrate and the polarized plate.
If the original external touch panel parts can be integrated with the LCD panel, the thin and lightweight of the panel may be achieved. In addition, when the touch panel is outside the liquid crystal, there is a physical space between the LCD and the touch panel. Therefore, the external light will be reflected between the liquid crystal panel and the bottom of the touch panel, resulting in the visibility in the outdoor environment reduce. If the external touch panel component can be integrated, the visibility of the outdoor can be suppressed.
The IN technology proposal was previously proposed, but because it is difficult to ensure the yield and display performance, the practicality is not enough. The reason is that the touch sensor function is embedded in the internal pixel on the array substrate. To this end, a complex semiconductor manufacturing process must be used, which will affect the rate of finished product. In addition, after the pixel is embedded in the touch sensor, the area part that can be used for display will be reduced, which is the main reason for the deterioration of the picture quality.
The appearance of new technologies has ushered in the integration of LCD and touch panels. As long as a simple transparent electrode pattern is formed between the color filter substrate and the polarized plate, it is easy to ensure the yield. In addition, the area of the effective display area in the pixel will not decrease, and it will hardly degrade the picture quality.
LCD integrated technology is popularized, so there is no need to use external touch panel parts. Manufacturers manufacturers are likely to transform from the original external touch panel into LCD panels and color filter. The original supply chain of purchasing external touch components will also be completely changed.
