Embodiment 2
[0068] The manufacturing process of the touch substrate for display in the second embodiment may be: first depositing a thin film of the photosensitive semiconductor layer, and then patterning the photosensitive semiconductor layer 106c by using a common mask plate through a patterning process. Then deposit a layer of metal thin film on the substrate, and use a common mask to pattern through a patterning process to form a pattern including the source-drain metal line 103 , the first electrode 106 a , the second electrode 106 b and the second detection line 105 . The subsequent process of forming the insulating layer 108 , the via hole 108 a and the color filter resin 101 is the same as that of the first embodiment.
[0069] The present invention also provides a liquid crystal display, including an array substrate and Figure 1a The shown touch substrate for display further includes a detection circuit for detecting the current in the first detection line and the second detectio...

The invention provides a basal plate for displaying, a manufacturing method thereof and a liquid crystal display. The basal plate for displaying comprises a source-drain metal wire, a first detection wire and a second detection wire, wherein the source-drain metal wire is vertical to the first detection wire, and parallel to the second detection wire; a sub-pixel area is formed in a crossing area of the source-drain metal wire and the first detection wire, and a photoelectric sensing device is formed in each sub-pixel area; a first electrode of the photoelectric sensing device is connected with the source-drain metal wire, a second electrode is connected with the first detection wire, and a photoelectric sensing semiconductor layer is connected with the first electrode, the second electrode and the second detection wire; the photoelectric sensing semiconductor layer can generate a current carrier when receiving an optical signal, so that the first electrode is conducted with the second electrode, and conducted with the second detection wire. By the basal plate for displaying, the problem that the touch display is not durable, and an indium tin oxide (ITO) film attached to the surface of the display can reduce the transmission rate of the display in the prior art can be solved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of liquid crystal display, and in particular to a touch substrate for display, a manufacturing method thereof, and a liquid crystal display. Background technique [0002] In recent years, touch displays have been increasingly applied to various terminal devices. A touch display is a sensor element consisting of a touch detection part and a touch screen controller, which are adhered to the surface of the display, using changes in the electric field of indium tin oxide (ITO) conductive glass and ITO film on the touch display to detect the position of the contact point, and transmit the position information of the contact point to the touch screen controller, and the touch screen controller transmits the received position information to the processor for processing. [0003] Existing touch displays include resistive, capacitive, infrared, surface acoustic wave, and electrostatic induction...
