Problems solved by technology

At the same time, the touch screen and display screen are independent components. When assembling electronic products, not only complex assembly processes are required, but also the thickness and weight of electronic products will be increased again.
Furthermore, one more assembly process means increasing the probability of defective products and greatly increasing the production cost of products

Embodiment Construction

[0026] The touch display screen will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 1-4 As shown, the touch display screen 10 of one embodiment includes a lower polarizer (second polarizer) 11, a first substrate 12, a TFT electrode 13, a liquid crystal module 14, a filter layer 15, a common electrode 16, and a second substrate 17. A transparent conductive layer 18 and an upper polarizer (first polarizer) 19 .

[0028] The lower polarizer 11 , the first substrate 12 , the liquid crystal module 14 , the filter layer 15 , the second substrate 17 and the upper polarizer 19 are stacked sequentially from bottom to top.

[0029] The liquid crystal module 14 includes two alignment films 142 disposed opposite to each other and a liquid crystal layer 144 sandwiched between the two alignment films 142 .

[0030] The TFT electrodes 13 are disposed on the surface of the first substrate 12 facing the liquid cryst...

Abstract

The invention provides a touch display screen. The touch display screen comprises a first substrate, a liquid crystal module, a filter layer, a second substrate and a first polaroid, wherein the first substrate, the liquid crystal module, the filter layer, the second substrate and the first polaroid are stacked in sequence; the surface, facing one side of the liquid crystal module, of the first substrate is provided with TFT (thin film transistor) electrodes; one side, facing the liquid crystal module, of the second substrate is provided with common electrodes; the TFT electrodes and the common electrodes are used for jointly controlling the arrangement state of liquid crystal molecules in the liquid crystal module; the touch display screen also comprises a transparent conducting layer arranged on the surface, backing on to one side of the liquid crystal module, of the second substrate or the surface of the first polaroid; the transparent conducting layer comprises a matrix and conducting nanometer wires filled in the matrix; the matrix is solidified transparent photosensitive resin; the transparent conducting layer is patterned to form touch electrodes; the touch electrodes are matched with the common electrodes to form a double-layer touch induction structure, and the double-layer touch induction structure is used for determining coordinates of a touch point. The touch display screen has the characteristics of being thin and low in production cost.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a touch display screen. Background technique [0002] A touch screen is an inductive device that can receive input signals such as touch. The touch screen has endowed information interaction with a new look and is a very attractive new information interaction device. The development of touch screen technology has aroused widespread concern in the information media circles at home and abroad, and has become a rising high-tech industry in the optoelectronic industry. [0003] At present, electronic products with a touch display function include a display screen and a touch screen located on the display screen. However, as a component independent of the display screen, the touch screen needs to be used according to the display screen when it is used in some electronic products that realize human-computer interaction. The size of the order is ordered, and then assembled...
