Embedded active matrix OLED (organic light emitting diode) touch panel

Abstract

The invention relates to an embedded active matrix OLED touch panel and belongs to the technical field of display screens. According to the embedded active matrix OLED touch panel, an OLED board comprises a lower touch sensor layer and an upper touch sensor layer, the lower touch sensor layer comprises a lower touch sensor matrix, the upper touch sensor layer comprises an upper touch sensor array, the distribution direction of the lower touch sensor array is perpendicular to that of the upper touch sensor array, and the lower touch sensor array and the upper touch sensor array compose a mutual-capacitance touch sensing unit for sensing touch signals. Therefore, touch signal sensing elements can be integrated with the OLED board to form an embedded touch panel. The embedded active matrix OLED touch panel is simple structure, thinner in thickness, lower in cost and applicable to more light-weight, thinner and shorter electronic products, and meanwhile, can effectively improve the penetrating degree of the panel, reducing rainbow rings and greatly improve usage experience of users.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to the technical field of light-emitting diode display screens, in particular to an embedded active matrix organic light-emitting diode touch panel. Background technique [0002] In current electronic products, display panels with touch functions are generally mounted on various smart handheld devices. Therefore, the requirements of electronic products for thinness, lightness and compactness are also imposed on touch panels. Through the efforts of manufacturers, solutions ranging from out-cell touch panels (Out-Cell Touch) to surface-embedded touch panels (On-Cell Touch), and even single glass touch (One Glass Solution, OGS) have emerged Appear. [0003] Among them, the conventional structure of the surface embedded touch panel (On-Cell Touch) is as follows: figure 1 shown. On-cell is to paste the touch sensor sensor and related film materials on the upper cover glass, an...

AI Technical Summary

Problems solved by technology

Its disadvantages are: poor panel penetration (Low transmittance); easy to produce rainbow pattern phenomenon (Moire), and the panel is thicker, and the cost is relatively high

OGS integrates the upper cover glass and the sensor into a single glass state and attaches it to the panel (Panel cell), so as to reduce the number of glass to two pieces, which can be reduced to a certain extent compared with the surface-embedded touch panel. The overall thickness of the panel reduces the production cost, but the single glass touch panel structure in the prior art also has the problems of poor panel penetration and rainbow pattern phenomenon
