Problems solved by technology

[0002] At present, most electronic devices do not have the function of display input, that is to say, electronic devices do not support external devices to directly input display data and display, and electronic devices cannot be used as displays
Some electronic devices that support the display input function can only enable the electronic device to have the function of display input by setting an independent display chip in the electronic device, and the cost is relatively high

Abstract

The embodiment of the invention discloses electronic equipment, which comprises a first transmission circuit connected between a graphics processor and a display panel and used for transmitting to-be-displayed data output by the graphics processor to the display panel; a second transmission circuit connected between a data interface and the display panel and used for transmitting to-be-displayed data input by external equipment connected to the data interface to the display panel; a controller connected with the first transmission circuit and the second transmission circuit and used for controlling the on-off state of the first transmission circuit and the second transmission circuit; and the display panel used for displaying the transmitted to-be-displayed data.

Description

technical field [0001] The embodiment of the present application relates to electronic technology, and relates to but not limited to an electronic device. Background technique [0002] At present, most electronic devices do not have a display input function, that is to say, electronic devices do not support external devices to directly input and display data, and electronic devices cannot be used as displays. For some electronic devices that support the display input function, the electronic device can only be equipped with a display input function by setting an independent display chip in the electronic device, and the cost is relatively high. Contents of the invention [0003] In view of this, the embodiment of the present application improves the internal original circuit of the electronic device and adds a transmission circuit for transmitting the data to be displayed of the external device, so that the electronic device has the function of supporting display input; be...
