Embodiment Construction

[0031] The specific implementation manners of the optical sensor embedded touch screen and the display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] An embedded touch display screen provided by an embodiment of the present invention includes a display area and a display light source used for display in the display area, such as figure 1 As shown, the display area has a plurality of touch areas 1 arranged in a matrix, touch scanning lines Scan corresponding to each row of touch areas 1, and touch reading lines Read corresponding to each touch area 1 one by one;

[0033] Each touch area includes at least one touch module 10 (one touch module is taken as an example in the figure for illustration), each touch module 10 includes a photosensitive unit 11 and a touch reading unit 12, and the output of the photosensitive unit 11 The terminal is connected to the input terminal of the t...

Abstract

The invention discloses an embedded touch display screen and a touch display system. The embedded touch display screen comprises a display light source for displaying in a display area, wherein the display area is provided with touch control areas which are arranged in a matrix form, touch control scanning lines corresponding to all lines of touch control areas, and touch control reading lines corresponding to the touch control areas one by one; each touch control area comprises at least one touch control module; the touch control modules comprise light-sensing units and touch control reading units; when the light-sensing units receive light, touch control signals are generated and supplied to the touch control reading units; when the touch control reading units are switched on under the control of the touch control scanning lines, touch control signals are output to the touch control reading lines by the touch control reading units; light received by the light-sensing units is light of a display light source reflected onto the light-sensing units by a touch-control body when the touch control body gets close to the touch display screen; the presence of touch control is determined through judgment of the magnitudes of signals on the touch-control reading lines, so that an optical sensing touch control function is realized; compared with a capacitive sensing touch control screen, the embedded touch display screen and the touch display system have the advantages that the problems of signal interference and signal delay are solved in the case of a large size.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to an embedded touch display screen and a touch display system. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. At present, touch screens roughly include: resistive sensing touch screens, capacitive sensing touch screens, optical sensing touch screens, etc., classified according to principles. According to the classification of the composition structure, the touch screen roughly includes: the touch screen with the touch screen hanging on the display panel (Out-cell touch panel), the touch screen with the touch screen on the display panel (On-cell touch panel), the touch screen with the touch screen embedded in the panel (In-cell touch panel) -cell touch panel). Among them, the structure in which the touch screen is embedded in the panel can not only reduce the o...
