Black and white screen display method and device based on Android platform and intelligent terminal

Abstract

The invention discloses a black and white screen display method and device based on Android platform and an intelligent terminal. The method comprises: selecting the size of the black and white screen according to the image display size generated on the Android platform, wherein the image display size matches with the size of the black and white screen; obtaining the Android display data generated on the Android platform; respectively converting the Android display data corresponding to every pixel into black and white display data corresponding to every pixel; caching the converted black and white display data to a queue, extracting data from the queue by a set real time course, outputting to the data interface of the black and white screen according to a preset frame rate; and displaying the black and white display data corresponding to every pixel on the black and white screen. The technical solution provided by the invention converts the Android display data into the black and white display data applicable to be displayed on the black and white screen, caches the black and white display data to the queue, avoids frame loss phenomenon and fluently displays the image generated by the Android platform on the black and white screen.

Description

technical field [0001] The invention relates to the field of visual equipment, in particular to a black and white screen display method, device and intelligent terminal based on an Android platform. Background technique [0002] At present, the Android display data generated by the Android platform is color display data corresponding to multiple data bits of each pixel. In order to transmit the color display data, the common interfaces of the display screen supported by the Android platform by default include: TTL (TransistorTransistorLogic, transistor-transistor Logic) interface, LVDS (Low-Voltage Differential Signaling, low-voltage differential signal) interface, EDP (Embedded DisplayPort, embedded display) interface, MIPI (Mobile Industry Processor Interface, mobile industry processor interface), etc. The communication methods of these interfaces are very similar, and the data transmission rate is even It can reach hundreds of Mbit / s, meeting the refresh rate of 60fps on ...

AI Technical Summary

Problems solved by technology

[0003] However, the data supported by the black and white screen is black and white display data corresponding to a single data bit of each pixel. In order to transmit the black and white display data, the black and white screen usually only uses SPI (Serial Peripheral Interface, Serial Peripheral Interface). The black and white screens of this type of interface are not supported, and the color display data generated by the Android platform cannot be displayed on the black and white screen; at the same time, since the data transmission rate of the SPI interface is only 2Mbit / s, and the image generated by the Android platform is relatively fast, Frame loss will occur, which cannot meet the black and white display requirements of the Android platform
