Touch unit, mutual capacitance touch screen and touch display device

Abstract

The invention discloses a touch control unit, a mutual capacitance touch screen and a touch display device, wherein the touch control unit comprises: a base substrate and a first touch electrode and a second touch electrode located on the base substrate and arranged crosswise. The touch electrode, the first touch electrode includes: a first sub-electrode and a second sub-electrode, the first sub-electrode and the second sub-electrode are arranged along the first direction, and the first sub-electrode and the second sub-electrode are electrically connected; The sub-electrodes include at least one first strip-shaped electrode, the second sub-electrodes include at least one second strip-shaped electrode, and the extension direction of the first strip-shaped electrode is not on the same straight line as the extension direction of the second strip-shaped electrode. The touch control unit provided by the present invention not only has better shadow elimination effect, but also can effectively avoid the appearance of moiré.

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. [0003] figure 1 It is a structural schematic diagram of a touch ...

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.
