Embedded touch display and manufacturing method thereof

Abstract

The invention provides an embedded touch display which comprises a thin film transistor array substrate, a color filtering array pattern substrate and a liquid-crystal layer, wherein the liquid-crystal layer is arranged between the thin film transistor array substrate and the color filtering array pattern substrate; and the color filtering array pattern substrate comprises a color filtering pattern layer and the filtering patterns are composed of a plurality of red materials, green materials or blue materials. For the embedded touch display, two adjacent filtering patterns on the color filtering array pattern substrate have different colors and at least one adjacent edges of the two adjacent filtering patterns are overlapped, the overlapped part comprises a material having a third color different from the colors of two adjacent materials so as to form a three-color laminated layer; and the three-color laminated layer can be used for improving the problems of light leak or colour mixture. The invention also provides a manufacturing method of the display.

Description

technical field [0001] The invention relates to a display, in particular to an embedded touch display and a manufacturing method of the display. Background technique [0002] Embedded touch panels can be divided into two types: On-cell touch and In-cell touch. The difference between the two is that In-cell is a method of embedding touch panel functions into LCD pixels. , On-cell is a method of embedding the touch panel function between the color filter substrate and the polarizer. [0003] Compared with the on-cell touch panel, the design of the in-cell touch panel is lighter and thinner, and has higher reliability. However, when the touch sensing component and the color filter are on the same side, since the lines of the transparent electrode of the touch sensing component and the transparent electrode of the color filter are too close, it is easy to cause poor response of the touch sensing component. Or the LCD driver is bad. [0004] Figure 1A A schematic cross-sectio...

Problems solved by technology

In addition, due to the high resolution requirement of the panel, in order to increase the aperture ratio, the width of the black matrix is ​​reduced, and the overall thickness of the touch sensing component layer and the color filter layer is increased, resulting in problems such as light leakage and color mixing.

[0007] In view of this, how to design a novel in-cell touch display to effectively solve the above-mentioned defects or deficiencies of light leakage and color mixing in order to increase the aperture ratio is a problem to be solved urgently by relevant technical personnel in the industry.
