Problems solved by technology

However, if the area of ​​the conductive pads and the distance between two adjacent conductive pads are large, the peripheral size of the in-cell touch screen will be larger, thereby affecting the overall size of the touch display device. In addition, the distribution of the conductive pads The larger area also requires more conductive adhesive, so the cost is higher

Embodiment Construction

[0038] As mentioned in the background art, in the scheme of electrically connecting the conductive pads on the liquid crystal panel to the integrated circuit through conductive glue, usually to prevent short circuit and mutual interference between adjacent conductive pads, the area of ​​the conductive pads and the distance between two adjacent conductive pads The distance between them is relatively large, which will lead to a large peripheral size of the embedded capacitive touch screen, which will affect the overall size of the touch display device. Moreover, the large area of ​​the conductive pads and the large distance between two adjacent conductive pads will also lead to a large distribution area of ​​the conductive pads, which will increase the required conductive glue and thus increase the cost. Therefore, the present invention discloses an electrical connection structure of a touch-control liquid crystal display device to solve the above problems.

Abstract

The present application discloses an electrical connection structure of a touch controlled liquid crystal display device, including: a first substrate; a plurality of first conductive pads on the first substrate, each of the first conductive pads being electrically connected with one first signal line; and at least one isolator between two adjacent first conductive pads. In the electrical connection structure of the touch controlled liquid crystal display device according to the present application, the isolator is arranged between two adjacent first conductive pads so that when the first conductive pads and the isolator are subsequently covered with conductive glue including conductive balls, the conductive balls in the conductive glue between two adjacent first conductive pads will not contact with each other to thereby ensure that the first conductive pads can be kept insulated from each other even if the conductive balls are distributed in the conductive glue at a high density.

Description

technical field [0001] The present invention relates to the field of liquid crystal display, in particular to an electrical connection structure of a touch liquid crystal display device. Background technique [0002] Liquid crystal display (LCD) technology is the first flat panel display technology to enter large-scale industrialization, and is currently a hot technology in the display industry. Since Austrian scientists first discovered the liquid crystal phenomenon in 1888, the epoch-making liquid crystal display came out in 1968. In the following decades, liquid crystal display technology continued to develop. After entering the 21st century, liquid crystal display technology has been further developed, and the development at this stage is mainly manifested in improving display quality, realizing energy saving and environmental protection, and integrating other functions. [0003] Since the world's first resistive touch screen appeared in 1974, touch technology has devel...
