Problems solved by technology

[0006] In order to solve the existing on-cell touch display products that have not yet seen pressure-sensing technology, it is urgent to fill the vacancy in this field, and the existing In-cell touch display provided by Apple Inc. integrates pressure on the backlight module. In the solution of the sensor function sheet, due to the defects of the backlight module such as low temperature resistance, tensile deformation, low surface hardness and easy scratching, the process is difficult, the yield rate is less than 70%, and the processing cost is high. The invention provides an On-cell touch display screen and portable electronic products

Embodiment 1

[0029] This example will specifically explain the On-cell touch display screen provided by the present invention, such as figure 2 As shown, it includes a protective panel 1 and a touch display module 2; the touch display module 2 and the protective panel 1 are installed in the metal middle frame 5 of the portable electronic product;

[0030] Among them, a pressure-sensing functional sheet 4 is also included; the pressure-sensing functional sheet 4 is pasted on the protective panel 1 and the touch display through the OCA (English full name: Optical Clear Adhesive, Chinese full name: Optical Clear Adhesive) adhesive layer 3 between module 2; from figure 2 It can be clearly seen from the figure that the upper and lower surfaces of the pressure-sensing functional sheet 4 are pasted with OCA adhesive layer 3; Such as Figure 4 As shown, the pressure-sensing functional sheet 4 includes a base layer 40 and a pressure-sensing electrode 41 formed on the base layer 40; ) to form a...

Embodiment 2

[0044] This example provides a portable electronic product, including the On-cell touch screen described in Embodiment 1. The on-cell touch display screen is installed in the metal middle frame 5 of the portable electronic product, specifically, such as figure 2 As shown, a step portion is formed on the periphery of the metal middle frame 5, and an adhesive glue 6 is provided on the step portion; the peripheral edge of the protective panel 1 is pasted on the adhesive glue 6 on the lower surface.

[0045] This example only improves the On-cell touch screen in the portable electronic product disclosed in the present invention, and the improvement has been specifically explained in Embodiment 1. Therefore, no more details.

[0046] In the On-cell touch screen provided by the present invention and the portable electronic product using the On-cell touch screen, the On-cell touch screen directly attaches the pressure-sensing function sheet 4 to the protective panel through the OCA...

Abstract

The invention provides an on-cell touch display screen and a portable electronic product so as to solve the problems that when the scheme of integrating a pressure inducting function piece on a backlight module of an existing In-cell touch display screen, the technology processing difficulty is large, the yield is smaller than 70%, and processing cost is high. The on-cell touch display screen comprises a protecting panel, a touch display module and a pressure inducting function piece. The pressure inducting function piece is attached between the protecting panel and the touch display module through an OCA adhesive layer. The pressure inducting function piece comprises a base layer and a pressure inducting electrode formed on the base layer. According to the on-cell touch display screen and the portable electronic product, the manufacturing process is simpler, the yield is higher and can reach 90% or above, and cost is lower.

Description

technical field [0001] The invention relates to the field of portable electronic products, in particular to the field of On-cell touch screens used in portable electronic products. Background technique [0002] Compared with the original method of separately disposing the touch screen on the display screen (liquid crystal panel), the research on integrating the function of the touch screen with the liquid crystal panel is becoming more and more popular. The integration of touch screen and LCD panel includes "In-cell" method and "On-cell" method. In-cell refers to the method of embedding the functions of the touch display module panel into the LCD pixels. On-cell refers to the method of embedding the function of the touch display module panel between the color filter substrate and the polarizer. Such as figure 1 As shown, its structure generally includes a protective panel 1 and a touch display module 2 ; the protective panel 1 and the touch display module 2 are bonded by ...
