Abstract

The invention provides a driving device compatible with various display protocol hardware interfaces. A driving circuit comprises a protocol compatible physical layer compatible with various display protocols, a plurality of GPIO interfaces and a plurality of data channels. Wherein the protocol compatible physical layer is provided with a multi-path signal input end and a multi-path signal outputend; the protocol compatible physical layer is used for being compatible with hardware interfaces of a plurality of display protocols, the input end of the protocol compatible physical layer is connected with the output ends of the hardware interfaces of different display protocols, and the output end of the protocol compatible physical layer is connected with one or more input end Pad windows ofthe GPIO interfaces; Wherein the input end Pad window of one or more of the GPIO interfaces is connected with the output end of the protocol compatible physical layer, and the output end of one or more of the GPIO interfaces is connected with the display module; Wherein the plurality of data channels are formed by a protocol compatible physical layer, a plurality of GPIO interfaces, a plurality ofGPIO interfaces and a display module.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving device compatible with multiple display protocol hardware interfaces. Background technique [0002] The display hardware interface of the mobile smart device completes the data transmission between the driver IC and the liquid crystal display (LCD). The hardware interface includes a physical interface and a logical data transmission protocol. LCDs of different products may support different hardware interface technologies, including but not limited to parallel interface parallel RGB, low-voltage differential signal (LVDS) serial interface and mobile industry processor interface-display serial interface MIPI-DSI, etc.; therefore, the driver IC is required The design is compatible with the above three technologies to meet the needs of different LCDs. [0003] In the prior art, in order to support the traditional practice of the three interface technologies, according to...
