Abstract

The invention discloses a touch electrode structure, a touch screen and a display device. The touch electrode structure includes a plurality of parallelogram-shaped self-capacitance electrode groups; wherein, each of the self-capacitance electrode groups includes two triangle-shaped and Self-capacitance electrodes insulated from each other and arranged complementary. It is equivalent to merging the existing four rectangular self-capacitance electrodes arranged side by side into two triangular self-capacitance electrodes arranged in a complementary manner under the premise of ensuring the same touch accuracy. Under the premise of precision, the number of self-capacitance electrodes is reduced, thereby reducing the number of wires connected to the self-capacitance electrodes one by one, which can increase the aperture ratio of the touch screen, reduce the frame width and the area occupied by the touch detection chip .

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch electrode structure, a touch screen and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. According to the principle, touch screens can be divided into capacitive sensing touch screens, resistive sensing touch screens and optical sensing touch screens, etc. Among them, capacitive sensing touch screens include self-capacitance sensing touch screens and mutual capacitance sensing touch screens. Compared with the mutual capacitance sensing touch screen, the self-capacitance sensing touch screen has a higher signal-to-noise ratio and higher accuracy of touch sensing. [0003] In the existing self-capacitance sensing touch screen, such as figure 1 As shown, there are a plurality of self-capacitance electrodes 101 arranged on the same lay...
