Abstract

The invention relates to the technical field of display, in particular to an integrated control module of a touch screen. The integrated control module of the touch screen comprises a touch panel and a display panel. The touch panel is arranged above the display panel, the display panel is fixedly mounted on a circuit board, a control module is further arranged on the circuit board, the touch panel and the display panel are respectively connected with the control module, the control module comprises a touch point sensing unit, a display driving unit, a processor unit and a memory, the touch point sensing unit is connected with the touch panel, the display driving unit is connected with the display panel, and the memory, the touch point sensing unit and the display driving unit are respectively connected with the processor unit. According to the technical scheme, the integrated control module has the advantages that a touch function of the touch panel can be realized without a computer or an operating system, the integrated control module is simple in structure and small in size, and accordingly can be packaged and integrated to a display terminal portion of equipment, and requirements of industrial automation on miniaturization and high integration level are met.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a display control module. Background technique [0002] Traditional touch screens must use a supporting computer, corresponding operating system and related programs to make one-to-one correspondence between touch commands and information or images on the display panel, so as to complete the touch control function. This input method allows users to perform various operations directly on the display panel without the keyboard, allowing users to obtain a more intuitive experience. In industrial occasions, the operation steps can be simplified, which is convenient for operation and increases safety. However, due to the need to cooperate with the computer and operating system, the input cost and the volume of the whole set of equipment cannot be effectively controlled, and it is difficult to well meet the requirements of high integration and miniaturization of the industrial automa...
