Embodiment Construction

[0019] see figure 1 , is a schematic side view of the first embodiment of the touch liquid crystal display device of the present invention. The touch liquid crystal display device 1 includes a first substrate 11 , a second substrate 12 opposite to the first substrate 11 , and a liquid crystal layer 13 sandwiched between the first substrate 11 and the second substrate 12 .

[0020] A first polarizer 111 is disposed on the surface of the first substrate 11 away from the liquid crystal layer 13 . A first capacitive sensing layer 14 and a second polarizer 15 are sequentially stacked on the surface of the second substrate 12 away from the liquid crystal layer 13 , wherein the first capacitive sensing layer 14 is adjacent to the second substrate 12 .

[0021] The second polarizer 15 has both polarization and dielectric properties and has a certain mechanical strength, so that the polarization effect can be realized, and the first capacitive sensing layer 14 is electrically insulate...

Abstract

The invention provides a touch-control liquid crystal display device which comprises a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer arranged between the first substrate and the second substrate and a capacitance sensing layer, wherein the capacitance sensing layer comprises a transparent conducting pattern arranged on the surface of the second substrate. The touch-control liquid crystal display device has low manufacturing cost, thin thickness, light weight and good display effect.

Description

technical field [0001] The invention relates to a touch liquid crystal display device. Background technique [0002] In recent years, with the development of humanization and simplification of operation, touch display devices with touch panels, especially touch liquid crystal display devices, are more and more widely used in production and life. Since the user can directly touch the touch-sensitive liquid crystal display device with hands or other objects to input information, the user's dependence on other input devices (such as keyboard, mouse, remote controller, etc.) is reduced or even eliminated, which greatly facilitates the user's operation. [0003] At present, touch panels usually include resistive, capacitive, acoustic, infrared and other types, which are generally in the form of rectangular transparent panels, and are arranged on the side of the display surface of the liquid crystal display device in a stacked manner. The circuit board and the like are connected ...
