Abstract

The invention discloses a touch liquid crystal panel. The touch liquid crystal panel comprises a color filer substrate and a transistor substrate. The color filter substrate comprises a first substrate, a sensing array, touch sensing circuit contact cushions and a color filter. The transistor substrate comprises a second substrate and a pixel unit. According to one embodiment, the first substrate comprises an upper edge area and a lower edge area which are the same in width. According to another embodiment, the touch sensing circuit contact cushions are arranged on the upper edge area and the lower edge area of the first substrate, and each electric conduction pattern in the sensing array is simultaneously connected to the corresponding touch sensing circuit contact cushions in the upper edge area and the lower edge area. According to another embodiment, each electric conduction pattern set of the sensing array includes two first electric conduction patterns and a plurality of electric conduction pattern lines arranged between the first electric conduction patterns.

Description

technical field [0001] The present invention relates to a touch liquid crystal panel, in particular to a touch liquid crystal panel which can avoid overlapping of a flexible circuit board of a touch sensing circuit and a flexible circuit board of a driving circuit. Background technique [0002] In recent years, thin and light flat panel displays have become widely used displays for various electronic products. In order to achieve the purpose of convenience, simple appearance and multi-functionality, many information products have changed from traditional input devices such as keyboards or mice to touch panels (Touch Panel) as input devices. [0003] With the rapid development of the technology of flat-panel displays and touch input devices, in order to allow users to have larger visual images and provide more convenient operation modes in a limited volume, some electronic products combine touch panels and display panels. combined to form a touch display panel. Because the ...
