Problems solved by technology

[0004] Among them, the separate attachment of the upper polarizer is likely to cause chromatic aberration due to the different expansion and contraction coefficients after bonding with the touch screen. It is also difficult to guarantee the accuracy of the angle between the absorption axes after the upper and lower polarizers are attached, which is not conducive to the display. There are many problems such as thinning and improving brightness, increasing production costs, etc.

Abstract

The invention provides a touch screen, a touch displayer and terminal equipment. The touch screen comprises a cover plate layer, a conducting film layer, a polarization layer and a protection layer, wherein the polarization layer is arranged between the cover plate layer and the protection layer and comprises a linear polarizer; and the conducting film layer is arranged between the cover plate layer and the polarization layer and / or between the protection layer and the polarization layer, generates a capacity change when touched and is used for realizing capacitive touch of the screen. Throughthe touch screen, the defect brought by an original upper polarizer attaching step can be avoided, thinning and brightness improvement of the displayer are promoted, and production cost is lowered.

Description

technical field [0001] The present application relates to the technical field of electronic devices, in particular to a touch screen, a touch display and a terminal device. Background technique [0002] With the rapid development of technology, more and more displays on terminal devices start to use touch displays. Using the touch display, the user can directly operate the host computer by operating on the display of the terminal device with fingers, thus making the human-computer interaction more straightforward and greatly simplifying the operation steps of the terminal device. [0003] Current touch displays generally include: a touch screen, an upper polarizer, a display device, and a substrate, etc. The touch screen, upper polarizer, display device, and substrate are sequentially bonded by an adhesive, and some touch displays also include a lower polarizer. [0004] Among them, the separate attachment of the upper polarizer is likely to cause chromatic aberration due t...
