Embodiment Construction

[0029] figure 1 It is a schematic diagram of a touch-sensitive liquid crystal display panel according to an embodiment of the present invention. Please refer to figure 1 The touch-sensitive liquid crystal display panel 100 has at least one display unit P1 (in this embodiment, a plurality of display units P1 ) and a plurality of touch-control units T1 . In this embodiment, the display unit P1 is a seven-segment display, but the practical application is not limited thereto. In other embodiments, the display unit P1 can also be a pixel unit in a general computer or TV screen display panel. In addition, the touch unit T1 can provide the user with a touch action, such as pressing or touching. The touch-sensitive liquid crystal display panel 100 includes a glass substrate 102 , an integrated chip 104 , a communication control interface 106 and a micro control unit 108 . Wherein the communication control interface 106 is bridged between the integrated chip 104 and the MCU 108, and...

Abstract

The invention discloses a touch liquid crystal display panel, which comprises a communication control interface, an integrated chip and a micro control unit, wherein the integrated chip drives at least one display unit according to display data, detects a touch action of a user and outputs a touch signal according to the touch action; the micro control unit transmits a state setting mark and setting data to the integrated chip; in addition, the communication control interface is used for transmitting the display data, the touch signal, the state setting mark and the setting data between the integrated chip and the micro control unit through a signal transmission protocol; and the integrated chip judges that the setting data is touch setting data or display setting data according to the state setting mark, and detects the touch action and drives the display unit according to the touch setting data and the display setting data. By the touch liquid crystal display panel, a communication interface can be simplified and the production cost can be reduced.

Description

technical field [0001] The invention relates to a touch-type liquid crystal display panel. Background technique [0002] In today's information age, human beings are increasingly dependent on electronic products. Laptop computers, mobile phones, personal digital assistants (Personal Digital Assistant, PDA), digital walkmans and other electronic products have become indispensable application tools in the life and work of modern people. Generally, electronic devices sold in the market are designed with a man-machine interface to provide users with inputting commands and make the electronic devices perform various functions in order to allow users to operate conveniently. In order to achieve more convenient portability, lighter volume and more user-friendly operation, in recent years, touch-sensitive liquid crystal display panels have been widely used in various electronic products, such as: Global Positioning System (GPS) , personal digital assistants, mobile phones (cellula...
