A black and white screen display method, device and intelligent terminal based on Android platform

Abstract

The invention discloses a black and white screen display method, device and intelligent terminal based on an Android platform. The method includes: selecting the size of the black and white screen according to the image display size generated in the Android platform, so that the image display size is adapted to the Describe the size of the black and white screen; obtain the Android display data generated in the Android platform; convert the Android display data corresponding to each pixel into the black and white display data corresponding to each pixel; cache the converted black and white display data into the queue, and use the set The real-time process extracts data from the queue and outputs it to the data interface of the black and white screen according to a predetermined frame rate; displays the black and white display data corresponding to each pixel on the black and white screen. The technical solution provided by the present invention converts the Android display data into black and white display data suitable for display on a black and white screen, caches the black and white display data into the queue, avoids the phenomenon of frame loss, and realizes the image generated in the Android platform on the black and white screen smooth display.

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 (TransistorTransistor Logic, 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 Similarly, the data transmission rate can reach hundreds of Mbit / s, which meets the 60fps refresh rate of the Andro...

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 Android platform does not support black and white screens of this type of interface, and the color display data generated by the Android platform cannot be displayed on the black and white screen; at the same time, because the data transmission rate of the SPI interface is only 2Mbit / s, and the image generated on the Android platform is relatively fast In this case, frame loss will occur, which cannot meet the black and white display requirements of the Android platform.
