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 ...
