Embodiment Construction

[0013] see figure 1 , is a schematic cross-sectional structure diagram 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 21 , a second substrate 22 opposite to the first substrate 21 , and a liquid crystal layer 23 sandwiched between the first substrate 21 and the second substrate 22 .

[0014] A first polarizing layer 211 is disposed on the surface of the first substrate 21 away from the liquid crystal layer 23 . A sensing layer 24 , a second polarizing layer 25 , a driving layer 26 and a protection layer 27 are sequentially stacked on the surface of the second substrate 22 away from the liquid crystal layer 23 . Wherein the sensing layer 24 is adjacent to the second substrate 22, and the second substrate 22 further includes a flexible circuit board 28, the flexible circuit board 28 is arranged on the driving layer 26, and is connected to the driving layer 26 and t...

Abstract

The present invention provides a touch liquid crystal display device, which includes a first substrate, a second substrate opposite to the first substrate, and a liquid crystal layer sandwiched between the first substrate and the second substrate. A sensing layer, a polarizing layer and a driving layer are arranged on the side of the second substrate away from the liquid crystal layer to form a coupling capacitor to realize touch display. The touch liquid crystal display device is thin in thickness, light in weight and has 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 liquid crystal 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, and the user's operation is convenient. [0003] At present, touch panels generally include resistive, capacitive, acoustic, infrared and other types, which are generally in the form of rectangular transparent panels, and are stacked on the side of the display surface of the liquid crystal display device. The circuit board and the like are connected to the liqui...
