Problems solved by technology

Due to the use of transparent double-sided tape, it is easy to produce an air layer, and an air layer entrained under the glass will increase the reflection by 8%, and the higher the reflection, the worse the display effect
Although the glass protective layer improves the hardness of the surface, it affects the sensitivity of the thin-film sensor, which is prone to misoperation, and the static electricity on the thin-film sensor cannot be exported, which further affects the misjudgment of operation instructions.
The LCD screen is located inside the casing, while other layers are located outside the casing. The layers on the surface of the LCD screen are heavy and thick, with many processing steps, high cost, difficult processing, and poor user experience.

Embodiment 1

[0014] Such as figure 1 As shown, the touch display screen includes a first thin film sensor layer 1, a liquid crystal screen 5 and a housing 6; the first thin film sensor layer 1 is bonded together with the liquid crystal screen 5 through the first OCA optical adhesive layer 2; the second A film sensor layer 1 and a liquid crystal screen 5 are installed inside the casing 6 , and the casing 6 is provided with flanges around the periphery, and the flanges are pressed against the outer surface of the first film sensor layer 1 .

[0015] When the first thin film sensor layer 1 is touched, an electronic signal will be sent back to the inside of the IC to realize the touch effect.

[0016] The first OCA optical adhesive layer 2 is used for bonding, which has good transparency, mature technology, and good bonding effect. There is no air layer, and the reflection is reduced by 8%, which improves the display effect.

[0017] The size of the capacitance is related to the conductive ar...

Embodiment 2

[0022] Such as figure 2 As shown, the touch display screen includes a first film sensor layer 1, a second film sensor layer 3, a liquid crystal screen 5 and a housing 6; the first film sensor layer 1 passes through the first OCA optical adhesive layer 2 and the second film sensor layer 3 Paste together, the second thin film sensor layer 3 is pasted together with the liquid crystal screen 5 through the second OCA optical glue layer 4, and the first thin film sensor layer 1, the second thin film sensor layer 3 and the liquid crystal screen 5 are installed on the shell 6 Inside, the shell 6 is provided with flanging around the periphery, and the flanging is pressed against the surface of the first film sensor layer 1 .

[0023] The first thin film sensor layer 1 and the second thin film sensor layer 3 are respectively coated with different shapes as capacitive sensing electrodes with conductive coatings, so that when a finger touches, the capacitive sensing value can be changed ...

Abstract

The invention relates to a display screen, in particular to a touch display screen. The touch display screen comprises a first film sensor layer, a liquid crystal display screen and a housing, wherein the first film sensor layer is attached to the liquid crystal display screen through a first OCA optical glue layer; the first film sensor layer and the liquid crystal display screen are mounted in the housing, and flangings are arranged on the periphery of the housing and press the outer surface of the first film sensor layer. The touch display screen is good in color, sensitive to touch, high in surface hardness, large in size, light and thin.

Description

technical field [0001] The invention relates to a display screen, especially a touch display screen. Background technique [0002] The existing touch display screen is sequentially stacked with a glass protective layer, a film sensor layer, a transparent double-sided adhesive tape, and a liquid crystal screen. Since the use of transparent double-sided tape is easy to produce an air layer, and an air layer entrained under the glass will increase the reflection by 8%, and the higher the reflection, the worse the display effect. Although the glass protective layer improves the hardness of the surface, it affects the sensitivity of the thin-film sensor, which is prone to misoperation, and the static electricity on the thin-film sensor cannot be exported, which further affects the misjudgment of operation instructions. The LCD screen is located inside the housing, while other layers are located outside the housing. The layers on the surface of the LCD screen are heavy and thick,...
