Title:
TOUCH CONTROL ELECTRODE STRUCTURE, TOUCH SCREEN AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/045340
Kind Code:
A1
Abstract:
A touch control electrode structure, a touch screen and a display apparatus. The touch control electrode structure comprises at least one touch control electrode group (10), wherein the at least one touch control electrode group (10) is arranged around a centre (20), each touch control electrode group (10) comprises a plurality of touch control electrodes (101), the plurality of touch control electrodes (101) in each touch control electrode group (10) are respectively arranged in a direction from a position near to the centre (20) to a position away from the centre (20), and the size of an end portion (012) of each of the touch control electrodes (101) away from the centre (20) in a circumferential direction is greater than the size of an end portion (011) of each of the touch control electrodes near to the centre (20) in a circumferential direction. The touch control electrode structure may be applied to a non-rectangular (irregular shape) touch screen and may effectively and completely cover the non-rectangular touch screen according to requirements, so that poor performances, such as inaccurate point report or poor linearity caused by imperfect coverage of the touch control electrode at edges or corners of the touch screen, can be avoided.
