Description of the Invention: [Technical Field] The present invention relates to a touch liquid crystal display device. [Prior Art] In recent years, with the 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 liquid crystal display device with a hand or other object to input a message, thereby reducing or even eliminating the user's dependence on other input devices (such as a keyboard, a mouse, a remote controller, etc.), the user can operate. When 刖, the touch panel usually includes a plurality of types of resistive type: capacitive type, acoustic wave type, infrared type, etc., which are generally in the form of a rectangular transparent panel, and are disposed on the display surface side of the liquid crystal display device in a stacking manner, and The flexible circuit board or the like is connected to the liquid crystal display device and the corresponding control device to realize the touch function. In the touch liquid crystal display device of the stacked structure, the two-liquid SB display device of the touch panel needs to be separately fabricated and then bonded together, and the three products are made higher. The touch panel is usually bonded to the liquid crystal display and the B surface by the adhesive layer. The touch panel and the adhesive layer increase the thickness and the weight of the touch liquid crystal display device. At the same time, because the touch panel and the adhesive layer absorb light such as light and reflection, the light transmittance of the liquid crystal display device is lowered, and optical interference is easily generated, causing the display image color to reduce its display effect. . ^ [Summary of the Invention] It is necessary to provide a touch panel with a thin thickness, light weight and good display effect. 200925955 Liquid crystal display device. A touch liquid crystal display device includes a first substrate, a first 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 disposed on a side of the substrate away from the liquid crystal layer to form a coupling capacitor for touch display. A touch liquid crystal display device includes a first substrate, a second substrate disposed opposite the first substrate, and a liquid crystal layer missing between the first substrate and the second substrate, the second substrate being remote from The liquid crystal layer side includes a driving layer, a sensing layer and a polarizing layer sandwiched between the driving layer and the sensing layer. Compared with the prior art, the second substrate surface of the touch liquid crystal display device has a sensing layer, a polarizing layer and a driving layer, and the polarizing layer is used as an insulating layer to form a coupling capacitor to realize a touch display function. The touch liquid crystal display device does not require an additional touch panel, and has low manufacturing cost, thin thickness, and light weight, which is advantageous for the thin and light development of the touch liquid crystal display device. At the same time, since the components such as the touch panel and the adhesive tape are not used, the light absorption, refraction, anti-reflection, and interference are effectively reduced, and the overall transmittance of the touch liquid crystal display device is high and the effect is not good. [Embodiment] Referring to Fig. 1, a cross-sectional structure of a first embodiment of a touch liquid crystal display device of the present invention is not intended. The touch liquid crystal display device 1 includes a first substrate 21', a second substrate 22 disposed opposite the first substrate 21, and a liquid crystal layer 23 sandwiched between the first substrate 21 and the second substrate 22. A first polarizing layer 211 is disposed on a surface of the first substrate 21 away from the liquid crystal layer 23 side. The second substrate 22 is disposed on the side of the surface of the liquid crystal layer 23 on the side of the surface of the layer 200930955. The sensing layer 24, a second bias 26 and a protective layer 27 are laminated in this order. The sensing layer 24 is adjacent to the second layer 22, and the second substrate 22 includes a second substrate 22, and the circuit board 28 is disposed on the driving layer 26, and the driving layer 26 is disposed on the driving layer 26. The electric power 24 is electrically connected, and is used for sensing the touch liquid crystal display and the sensing layer signal to the external controller (not shown). . Touch generated by the 罝 1 Please refer to Figure 2 for a touch LCD display. The sensing layer 24 is formed by a plane of a uniform transparent guide 1 adjacent to the second substrate: printed on the side of the second polarized light a, such as printing an indium tin oxide film into "the sensing layer 24 includes a plurality of The sensing line 24 is a transparent conductive strip parallel to each other, and the side of the double polarizing layer 25 of the complex line 241 is arranged at intervals. The sensing line 241 is opposite to the sensing layer 24 at the first driving layer 26 They are respectively located on both sides of the second offset 3, and the driving layer 26 is also formed by the indium tin oxide film printed on the "first polarizing layer 25. The driving layer 26 includes a plurality of parallel-shaped elongated axes 261, and the plurality of driving lines 261 are arranged in a row at the other side of the second polarizing layer 25, and are spatially perpendicular to the plurality of sensing lines 241. Insulation intersects. ♦ The second polarizing layer 25 is an insulating optical film. A via hole 253 penetrates through the sensing layer 24, the polarizing layer 25, and the driving layer 26. The plurality of sensing lines 241 of the sensing layer 24 are electrically connected to the flexible circuit board 28 via the vias 253, and are further connected to an external capacitive sensing circuit (not shown). The drive layer 26 is also coupled to a drive voltage source (not shown) by the flexible circuit board 28. The flexible circuit board 28 independently transmits the signals of the sensing layer 24 and the driving layer 26. 8 200925955 The sensing layer 24 and the driving layer 26 form a coupling capacitor by using the second polarizing layer 25 as an insulating layer. The complex sensing line 241 and the complex driving line 261 intersect perpendicularly on different planes to form a plurality of capacitive sensing nodes 200, each capacitive sensing node 2 〇〇 indicating a difference in the plane of the touch liquid crystal display device 1 coordinate. Each capacitive sensing node 2 receives an input from a target capacitor that contacts the capacitive sensing node 200. Contacting the capacitive sensing node 200 affects the capacitance of the capacitive sensing node 2〇〇. The working principle of the touch liquid crystal display device 1 is as follows: the driving voltage source scans the driving line 261 one by one, and the capacitance sensing circuit always senses the plurality of sensing lines 24 of the sensing layer 24 to drive the driving voltage source. When a drive line 261 is driven, the capacitance of each capacitive sensing node 2 is coupled to the complex sense line 241, which senses all of the parallel complex sense lines 241. When the external sensing touches the capacitive sensing node 2, the capacitance of the capacitive sensing node 200 changes, and the capacitive sensing circuit senses the capacitance of the electrical sensing node 2 by the sensing line 24ι The change corresponding to the change of the capacitance is the output of the control nickname to the external controller, thereby realizing the control of the capacitive sensing liquid crystal display device 1 for each capacitive sensing node 2 . Compared with the prior art, the sensing layer 24 and the driving layer 26 are printed on both sides of the second polarizing layer 25 of the touch liquid crystal display device i of the present invention, and the first polarizing layer 25 is used as an insulating layer to form a complex coupling. The capacitor is used for the touch function. The touch LCD display does not require an additional touch panel, and the steps of re-manufacturing the insulating layer necessary for the touch panel are omitted, so that the manufacturing cost is low and the thickness is thin. The light weight is beneficial to the development of the thin and light touch display liquid crystal display device. At the same time, since the components such as the touch panel and the adhesive tape are not used, the light absorption, refraction, reflection, and interference are not effectively reduced, and the touch liquid crystal display device is good. 1 is a high-profile overall light transmittance and display effect.

The touch liquid crystal display device 2 and the touch liquid crystal display device of the first embodiment! The structure is substantially the same, and the main difference is that the touch (tetra) crystal display device 2 includes two flexible circuit boards 38, and the flexible circuit board 38 electrically connects the driving layer % and the sensing layer %, respectively. The touch liquid can be realized by setting the (four) layer % to the other side of the second polarizing layer 35 without providing a via hole.

The main difference is that the touch liquid crystal display device 3 includes a "γ"-shaped flexible circuit board 48'. Layer 44 is used for signal transmission and there is no need to provide vias.
