Problems solved by technology

[0003] Because the display system usually adopts a single-chip microcomputer system, which is completely independent from the operating system of the PC, and the existing touch screen control method is based on the control of the operation of the touch screen by the PC operating system, so it is impossible to control the operation of the display system through touch actions. controls, are not user-friendly, and do not integrate touch functionality

Embodiment 1

[0018] Embodiment 1: The touch screen is usually placed on the surface of the display screen to sense external touch information and send touch coordinate signals. The flow chart of the control method of the touch screen provided by the present invention is as follows: figure 1 shown. Receive the touch coordinate signal (step 1) that touch screen sends; The touch screen control system of the present invention judges whether the user's current touch operation is for the operation of the OSD menu event or for the operating system event by judging the processing level of the current response event. If the response event of the OSD menu is a priority level, it means that the current user's operation is aimed at the OSD menu, then the touch coordinate signal is encoded according to the first predetermined rule to generate a serial port signal (step 2); the first predetermined rule is according to the OSD The encoding rules predefined by each response event of the menu; responding ...

Embodiment 2

[0023] Example 2, such as figure 2 As shown, in this embodiment, the control system of the touch screen includes a main control module, a signal processing module and a computer module.

[0024] The main control module receives the touch coordinate signal of the touch screen; judges the processing level of the current response event, if the response event of the OSD menu is a priority level, then the touch coordinate signal is converted into a serial port signal of the first encoding rule and sent to the signal processing module; otherwise, Send the touch coordinate signal to the computer module; the signal processing module decodes the serial port signal according to the first predetermined rule after receiving the serial port signal sent by the main control module; the first predetermined rule is determined according to each response event of the OSD menu a predefined encoding rule; and responding to the serial port signal. As an embodiment, after the computer module recei...

Embodiment 3

[0028] Example 3: image 3 It is a system block diagram of a touch screen system, including a display screen, a touch screen, a power supply module, and a touch screen control system. The touch screen control system includes a computer module, a main control module, and a signal processing module. After the system is powered on, the main control module receives the external start-up command sent by the remote control or the button, then sends the power switch control signal to the power module, and then turns on the timing control switch of the power supply and the standby power consumption control switch to ensure the power consumption of the entire system. Subsequently, the main control module sends a power-on command to the signal processing module, and finally sends a power-on command to the computer module and the touch module.

[0029] The touch screen is placed on the surface of the display screen to sense external touch information, and the touch module sends out USB s...

Abstract

The invention provides a touch screen control method, comprising the following steps of: firstly, receiving a touch coordinate signal, and judging the processing level of a current response event; if the response event of an OSD (on screen display) menu is prioritized, coding the touch coordinate signal according to a first predetermined rule to generate a serial port signal; and responding to the serial port signal. The invention further provides a touch screen control system, comprising a master control module and a signal processing module. The master control module is used for receiving the touch coordinate signal, judging the processing level of the current response event, if the response event of the OSD menu is prioritized, coding the touch coordinate signal according to the first coding rule into the serial port signal, and transmitting the serial port signal to the signal processing module, otherwise, transmitting the touch coordinate signal to a computer module; and the signal processing module is used for responding to the serial port signal and implementing touch-control operations on the OSD menu. The invention implements the touch control on the OSD menu.

Description

technical field [0001] The invention relates to the field of electronic appliances, in particular to the control technology of a touch screen. Background technique [0002] The current touch screen control system mainly realizes the touch function based on the operating system, but the display system part of the display screen has not yet realized the touch operation, such as adjusting the brightness of the screen and adjusting the size of the sound through the touch action , switch the channel of the input source, switch channels, OSD system settings and other operations. The functions of these display systems usually display various functions to the user through an OSD (On Screen Display, on-screen menu adjustment mode) menu, and then the user operates the OSD menu through a remote controller or a keypad. [0003] Because the display system usually adopts a single-chip microcomputer system, which is completely independent from the operating system of the PC, and the exist...
