Single layer touch control sensing structure and touch control display panel using the same

Abstract

The invention provides a single-layer touch sensing structure comprising a conducting layer. The conducting layer is provided with at least one induction block. The induction block is provided with a plurality of grooves. The induction block is divided into a plurality of electrodes by the grooves. A plane capacitance structure is formed between two optional adjacent electrodes. Adopting the single-layer touch sensing structure, the invention further provides a touch display panel that comprises the conducting layer, a telecommunication circuit module and a display unit. The conducting layer is provided with a plurality of grooves and the induction block is divided into a plurality of electrodes. The telecommunication circuit module has electric connection with a plurality of electrodes. The display unit has coupling with the telecommunication circuit module to determine a touch position according to the capacitance change of the sensing area. The display unit is arranged below the conducting layer.

Description

technical field [0001] The present invention relates to a sensing structure and a touch panel, in particular to a single-layer touch sensing structure in which a plurality of planar capacitors are formed on a single-layer conductive layer and a touch display panel using the structure. Background technique [0002] Touch panels originated in the 1970s when the U.S. military developed them for military use. In the 1980s, the technology was transferred to civilian use, and then developed into various uses. Traditional electronic computing devices (such as computers) use peripheral devices such as keyboards or mice as input interfaces. However, these peripheral input devices are too large and difficult to carry, which is likely to cause a major obstacle to the thinning of electronic products. Due to the demand for thinner electronic devices, touch panels are gradually becoming more and more popular in portable electronic products. In addition, in addition to the application of ...

Problems solved by technology

Although this technology is simple, it still has the following disadvantages: First, the resistive touch panel has a two-layer structure, so it still has a certain thickness.

Second, the above-mentioned technology is also easy to cause screen wear and tear. If coatings are added to protect the screen or reduce reflection, it will cause poor light transmission.

Third, the hand-shadow effect (hand-shadow effect) is also easy to make the sensor judge wrong
