Problems solved by technology

[0005] The above solution endows LCD TV with touch function, which can meet the needs of users for touch control on the display screen, but it only has some control functions for controlling the display, and does not have the function of switching between LCD TV and other operating systems at will, and there is no other Some of the practical functions, such as random drawing and drawing, cannot meet the needs of meetings and other scenes, and the LCD TV equipment with touch function has a higher price than the traditional ordinary LCD TV, and now the LCD TVs in general homes and offices are It only has display function. If you need LCD TV with touch function, you need to replace the original LCD TV equipment, which will increase the upgrade cost. Moreover, if the LCD TV equipment with touch function is damaged, you need to replace the whole equipment such as touch screen and controller. , the maintenance cost is high, and the controller and touch-sensing device used for a certain display device cannot be used for other display devices, and the scope of application is limited
