Problems solved by technology

[0003] Since at least one additional touch electrode layer is required to sense the touch signal, and an additional insulating substrate is required to be bonded to the liquid crystal display panel, the above-mentioned touch display panel has advantages in cost, bonding rate, lightness and wiring The consistency will decrease relatively
On the other hand, the above-mentioned additional touch electrode layer cannot be disposed under the liquid crystal layer, otherwise the touch signal will not be...

Abstract

The invention provides a liquid crystal display panel with an operation sensing function and a display device thereof. The liquid crystal display panel includes a display area and at least one operation sensing area not used for display. The operation sensing area includes at least one first electrode and at least one second electrode, wherein the first electrode of the operation sensing area doesnot receive pixel voltages, and the second electrode of the operation sensing area does not receive common voltages, so that the first electrode and/or the second electrode of the operation sensing area are used for sensing a sensing signal generated when a touch object touches or approaches the operation sensing area. According to the liquid crystal display panel, a touch control key function can be provided for the liquid crystal panel by only changing wiring layout, and an additional transparent touch control electrode layer does not need to be attached on an insulating substrate so that the yield of manufacture procedures of the touch control liquid crystal display panel can be improved, and manufacturing costs can be reduced.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, relates to a liquid crystal display panel and a display device thereof which do not need to additionally design a transparent touch electrode layer on an insulating substrate but have an operation sensing function. Background technique [0002] At present, liquid crystal display devices with touch function generally bond the liquid crystal display panel and the touch panel to form a touch display panel, wherein the touch panel has a transparent insulating substrate (for example, a plastic film or a glass substrate) and At least one touch electrode layer (for example, an ITO layer) plated on the insulating substrate. [0003] Since at least one additional touch electrode layer is required to sense the touch signal, and an additional insulating substrate is required to be bonded to the liquid crystal display panel, the above-mentioned touch display panel has advantages ...
