Abstract

The invention discloses a sensing structure of a liquid crystal display, which comprises a first baseplate, a second baseplate, a sensing unit and a flexible printed circuit board. The sensing unit is arranged above the first baseplate and is suitable for producing a touch signal when the sensing unit is touched. The flexible printed circuit board is provided with a first end and a second end; the first end is provided with a first copulae and a second copulae, wherein, the first copulae is positioned above the first baseplate and is in electric connection with the sensing unit; the second copulae is connected to the second baseplate. The invention uses the same flexible printed circuit board to be in electric connection with the sensing unit, a chip and a signal processing system, thereby reducing the material use and the times for thermocompression bonding; if the invention is matched with a contact control unit integrated with the display for use, the whole thickness of the liquid crystal display can also be reduced further in order that the final product meets the development trend of the thin and light type of a flat panel display device.

Description

technical field [0001] The invention relates to a sensing structure, in particular to a sensing structure applied to a liquid crystal display. Background technique [0002] Due to the continuous advancement of optoelectronic technology and the digitalization of image display technology, various displays can be seen everywhere in daily life. Liquid crystal displays have been widely used in various communication or electronic products because of their advantages such as high image quality, thinness, low power consumption, and no radiation. They have gradually replaced traditional cathode ray tube displays and become the mainstream in the display market. [0003] The combined application of the liquid crystal display and the sensing unit can provide a touch function. In this way, the electronic product can save buttons or other devices and assemblies with similar functions, and can accommodate a larger-sized display panel under the same product size specification.
