TERMINAL TOUCH DETECTION METHOD AND EMBEDDED DISPLAY SCREEN HAVING TOUCH FUNCTION

摘要

The present invention relates to a built-in display screen, a terminal and a touch detection method having a touch function, wherein the display screen has an upper substrate (11), a lower substrate (12) And a liquid crystal display layer (13). The touch electrode layer 14 is formed between the liquid crystal display layer 13 and the upper substrate 11 and includes a plurality of electrodes 140 arranged in an array. The drive selector 15 is provided between the upper substrate 11 and the lower substrate 12 and is connected to the electrode 140 in a corresponding manner by a plurality of lead wires 150. The touch controller 16 is connected to the upper substrate 11 and the lower substrate 12 and is connected to the drive selector 15 by the selection signal line 160 and the scan signal line 161 and the total of the selection signal line 160 and the scan signal line 161 The quantity is less than the total quantity of lead wires (150). Through the above-described method, the present invention can reduce the number of lead wires 150 to be drawn into the touch controller 16.
