TOUCH DISPLAY SCREEN, METHOD FOR MANUFACTURING DISPLAY ELECTRODE OF THE TOUCH DISPLAY SCREEN, DISPLAY ELECTRODE AND ELECTRONIC DEVICE

摘要

A touch display screen, a method for manufacturing a display electrode of the touch display screen, a display electrode and an electronic device are described. In the touch display screen, the electrode in the first direction and the electrode in the second direction are connected to the touch detecting unit, and the touch detecting unit and the display control unit operate in a time-sharing manner. Thus, a part of the display electrode can be multiplexed, and it is unnecessary to provide an additional touch-sensitive layer to detect the touch on the touch display screen, so the structure of the touch display screen is simplified; because the touch-sensitive layer is omitted, the touch display screen has better transmittance; and because the touch detecting unit and the display control unit operate in a time-sharing manner, the detection on the touch and the control on the display will not affect mutually.

主权项

1. A touch display screen, comprising a cover plate, a color filter, a liquid crystal layer, a display electrode, a substrate and a backlight unit which are stacked sequentially from top to bottom, wherein:
the touch display screen further comprises a touch detecting unit and a display control unit; the display electrode comprises an electrode in a first direction and an electrode in a second direction which intersects with the first direction; the electrode in the first direction and the electrode in the second direction are connected to the touch detecting unit, the touch detecting unit is adapted to detect mutual capacitance formed between the electrode in the first direction and the electrode in the second direction, and determine a touch on the touch display screen based on the detected mutual capacitance; the display electrode is further connected to the display control unit, the display control unit is adapted to control the display electrode to perform liquid crystal display; and the display control unit and the touch detecting unit operate in a time-sharing manner.
