Touch liquid crystal module and integrated touch baseplate thereof

Abstract

The invention relates to an integrated touch baseplate which comprises a transparent baseplate, an active element array and a sensing array. The sensing array is configured between the active element array and the transparent baseplate and comprises a plurality of sensing pads, a plurality of leads, an insulating layer and a plurality of conductive connecting parts. An insulating layer is positioned between the leads and the sensing pads, and all the sensing pads are positioned between the insulating layer and the transparent baseplate. All the conductive connecting parts are positioned in the insulating layer and connected between the sensing pads and the leads. In addition, the invention also provides a touch liquid crystal module comprising the integrated touch baseplate.

Description

Technical field [0001] The present invention relates to a liquid crystal display (Liquid Crystal Display, LCD), and more particularly to a touch-sensitive liquid crystal module (touch-sensitive liquid crystal module) and an integrated touch-sensitive substrate (LCD). ). Background technique [0002] Touch-sensitive LCD is a liquid crystal display with both image display and data input functions. At present, many electronic equipment (electronic equipment), such as mobile phones and personal digital assistants (PDA), etc. Hand-held electronic devices and computers are equipped with touch-sensitive liquid crystal displays. Therefore, touch-sensitive liquid crystal displays have been widely used by the general public. [0003] The main components of a touch liquid crystal display include a touch liquid crystal module, and a general touch liquid crystal module includes a liquid crystal module (LCM), a touch substrate and a cover lens. The touch substrate is arranged between the liqui...

Problems solved by technology

[0005] In the process of bonding the liquid crystal module, touch substrate and cover glass together, not only must the three be aligned with each other, so that the relative positions of the three are correct, but also the liquid crystal module and the touch There should be no air bubbles between the substrates, and between the touch substrate and the cover glass, otherwise it will cause uneven color (mura) on the screen, which will damage the picture quality of the touch LCD

[0006] However, both the liquid crystal module and the touch substrate are usually made of a glass substrate, so the texture of the liquid crystal module, the touch substrate and the cover glass are very hard, so that during the lamination process, It is difficult for the touch substrate to be bonded to the liquid crystal module and the protective glass evenly, resulting in air bubbles easily appearing between the liquid crystal module and the touch substrate, and between the touch substrate and the protective glass, resulting in poor quality of the current touch LCD. Yield is low

[0007] Secondly, after the liquid crystal module, touch substrate and protective glass are bonded together to complete the touch liquid crystal module, once the completed touch liquid crystal module is found to be a defective product, such as the liquid crystal module, touch substrate and Serious misalignment (mismatch) occurs due to misalignment of the protective glass, or air bubbles appear in the touch LCD module. It is difficult to disassemble the defective touch LCD module for rework.

[0008] Specifically, since the liquid crystal module, the touch panel and the cover glass are attached to each other through an adhesive, and the texture of the three is quite hard, if the bad touch LCD module is dismantled If it is opened, the liquid crystal module, touch substrate and cover glass will retain residual adhesives that are not easy to remove, and when disassembled, it is very likely that the liquid crystal module, touch substrate or cover glass will be broken due to improper force

Therefore, for defective touch LCD modules completed due to lamination failure, most of them are disposed of in the form of scrapping
