Touch unit, mutual capacitive touch screen and touch display apparatus

Abstract

The invention discloses a touch unit, a mutual capacitive touch screen and a touch display apparatus. The touch unit comprises a substrate and first and second touch electrodes located on the substrate and crossly arranged; the first touch electrode comprises a first sub-electrode and a second sub-electrode; the first sub-electrode and the second sub-electrode are arranged in a first direction andelectrically connected; the first sub-electrode at least comprises a first stripline electrode; the second sub-electrode at least comprises a second stripline electrode; and an extension direction ofthe first stripline electrode and an extension direction of the second stripline electrode are not on the same straight line. The touch unit provided by the invention not only has a relatively good shadow elimination effect but also can effectively avoid the occurrence of moire.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch control unit, a mutual capacitance touch screen and a touch display device. Background technique [0002] At present, products such as mobile phones and tablet computers on the market all use touch screens, and the way of using touch is also a mainstream direction in the future. Among them, the mutual capacitive touch screen has the characteristics of directness, high efficiency, accuracy, smoothness, and fashion, which greatly improves the efficiency and convenience of human-computer dialogue, and has become a research and development hotspot of the mutual capacitive touch screen. The smallest unit for sensing touch on the mutual capacitance touch screen is the touch unit, and the design of the touch electrodes in the touch unit determines the performance of the mutual capacitance touch screen.

Problems solved by technology

However, since the gaps between the dummy electrodes 10 and the touch electrodes 1 and 2 are regularly arranged, taking the first touch electrode 1 as an example, the moiré patterns at the edges of the first touch electrodes 1 in the same column are connected to each other. , and arranged on the same straight line, a longer vertical moiré area 12 will be formed at this time, that is, the moiré phenomenon is obvious

[0008] It can be seen that the touch unit provided by the prior art cannot avoid the appearance of moiré while ensuring a better shadow elimination effect.
