Abstract

The invention discloses a sensing structure of display, which comprises a display module, a sensing unit and a chip, wherein the display module comprises an effective display region, the sensing unit is arranged above the display module and covers at least part of the electric display area, the chip is arranged above the display module and outside one effective display region. The invention directly arranges the chip above the display module to simplify process, reduce cost and reduce circuit space. The invention arranges a cover plate on the sensing unit to form a containing space for the cover sheet to contain the chip and prevent the whole thickness increase caused by the chip. The invention can use a touch controller combined with the display module to further improve the integrality of the sensing unit and reduce the thickness of the sensing structure, thereby reducing weight, elements and cost.

Description

technical field [0001] The invention relates to a sensing structure, in particular to a sensing structure for 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; among them, liquid crystal displays have been widely used in Various communication or electronic products, and gradually replace the traditional cathode ray tube display, become the mainstream in the display market. [0003] In order to increase the interaction with users and the added value of products, some LCD displays will add touch functions, allowing users to directly click on the desired function on the display of the electronic product, or even handwriting input directly on the display various characters or symbols. In this way, the electronic product can save the setting of buttons or other function buttons, and can accommodate a larg...
