Problems solved by technology

[0004] However, general-purpose touch input devices often have only one signal output interface. To develop a multi-channel touch panel requires the cooperation of touch input device suppliers, adding output interfaces and customizing interface protocols to realize diversified processing of touch coordinate information transmission and increase touch input. Control the development process of the tablet and the cost is relatively high

Abstract

The invention discloses a touch panel control circuit and a touch panel. The touch panel control circuit includes a touch adapter module, a main chip and a signal source interface. An input interfaceof the touch adapter module is used for connecting an output interface of touch input equipment, and receiving a first touch coordinate signal sent by the touch input equipment from the output interface. A first transmission interface of the touch adapter module is connected with a touch information transmission interface of the main chip. A second transmission interface of the touch adapter module is connected with the signal source interface. The touch adapter module is used for receiving, from the first transmission interface, a signal distribution instruction sent by the main chip from thetouch information transmission interface, and sending a second touch coordinate signal, which corresponds to the first touch coordinate signal, from the first transmission interface and / or the secondtransmission interface according to the signal distribution instruction. By implementing the embodiment of the invention, the universal touch input equipment can be used, a development process of thetouch panel can be simplified, and costs can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of touch input, and in particular to a touch panel control circuit and a touch panel. Background technique [0002] In the prior art, a touch panel with a large screen and capable of man-machine interaction has been widely used in multi-person interaction scenes such as teaching scenes and meeting scenes. In order to meet the multi-functional requirements in these scenarios, some touch panels are also equipped with signal source interfaces, allowing access to multiple signal sources, such as accessing external computer equipment, displaying the display screen of the external computer equipment on the touch panel, and The user can operate the display screen of the external computer device on the touch panel; or connect a computer module with an independent operating system, so that the touch panel has a dual-system operation interface. [0003] When the user switches the display channel...
