Abstract

The invention provides a liquid crystal display and a preparation method of the liquid crystal display. A touching button pattern is manufactured on a pre-arranged region of the interior of the liquid crystal display or on a pre-arranged region of the outer surface of the liquid crystal display and is visible when being observed outside. The liquid crystal display with a touch button function reduces the process that pattern wiring is conducted on the display touch button on a base plate of the liquid crystal display, ensures that the whole area of the base plate is occupied when electrodes with inducting-touching-controlling functions are wired, increases electrode-wiring wire distances and the wired area when the electrodes with the inducting-touching-controlling functions are wired is increased. The larger the wiring area of the electrodes with the inducting-touching-controlling functions is, the stronger the signal intensity is. Therefore, the liquid crystal display and the preparation method of the liquid crystal display weaken or eliminate signal interference between electrode wiring. Meanwhile, the liquid crystal display and the preparation method of the liquid crystal display reduce wiring on a printed circuit board (PCB), and ensure that wiring of the PCB is simplified.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a liquid crystal display screen with a touch button function and a manufacturing method thereof. Background technique [0002] At present, most of the liquid crystal display screens with the touch key function realize the touch function through the electrode wiring on the substrate in the liquid crystal cell. At present, one solution for implementing the touch function by using electrode traces is that the electrode traces on the substrate of the liquid crystal display screen that sense the touch function surround the electrode traces that display button patterns. The electrode traces for sensing the touch function and the electrode traces for displaying button patterns are connected to the traces on the PCB through pins. Corresponding wiring, and the number of pins on the LCD screen in the solution is relatively large. [0003] Therefore, in the existing liquid crystal disp...
