Problems solved by technology

Although the above-mentioned electrode layout structure is simple, when the user uses the touch screen, there will be a problem of floating, that is, if the user stands on the ground and directly operates the touch screen on the palm of the hand, the sensitivity of the touch screen is better because the human body is directly grounded; The touch screen is used in the car. Since the user cannot be directly grounded at this time, the sensitivity of the touch screen will decrease.
Therefore, if the use environment of the touch screen is changed, it may cause the suspension problem of the touch screen

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the drawings and embodiments.

[0012] Please refer to figure 1 with figure 2 As shown, the present invention relates to an electrode layout of a touch screen. The touch screen 1 mainly includes a substrate 10 and an electrode layer 11 provided on the substrate 10. The electrode layer 11 is provided with a cover plate 12, and the cover plate 12 is With LCD screen 13. The electrode layer 11 is composed of a plurality of electrodes 110 in the shape of a rhombus combination, and they are arranged crosswise along the longitudinal and transverse directions of the substrate 10. The electrode layer 11 can be arranged on the upper and lower sides of the substrate 10 respectively. It can be arranged on the same side of the substrate 10, that is, on the upper side. In this case, an insulating layer needs to be provided between the two electrode layers 11. Whether the electrode layers 11 are arranged on bot...

Abstract

The invention relates to a touch screen electrode layout. A touch screen mainly comprises a substrate and an electrode layer arranged on the substrate, a liquid crystal display screen is arranged on a cover plate which is arranged on the electrode layer, the electrode layer consists of a plurality of electrodes in a diamond combination form, and the electrodes are in a longitudinal-transverse intersection array along the substrate and partially hollowed out. By the touch screen electrode layout, the problem of suspension of the touch screen is solved, and linearity of the touch screen is greatly improved; and further, compatibility between the electrode layer and the liquid crystal display screen is enhanced.

Description

technical field [0001] The invention relates to an electrode layout of a touch screen, in particular to an electrode layout of a capacitive touch screen. Background technique [0002] With the development of science and technology, touch screens have gradually replaced mechanical button panels as new operating interfaces for electronic devices such as mobile phones and notebooks. Touch screens include resistive touch screens, infrared touch screens, and capacitive touch screens. They obtain coordinates in different ways, and capacitive touch screens are used in more and more products because of their better light transmittance, clarity, and reliability. . [0003] An important component structure of the capacitive touch screen is the electrode layout. The electrode layout of the capacitive touch screen commonly used now includes the X-axis sensing electrode and the Y-axis sensing electrode. Rows and several columns are arranged sequentially, and one column of X-axis sensin...
