基于SPI通信环境光控制技术

Ambient Light Control Technology Based on SPI Bus

为了解决液晶屏幕图像通过LED灯条延伸扩展显示效果,以及LED灯条实时同步显示画面颜色的问题,提出了一种基于SPI通信环境光控制技术方案,利用软件算法实现了对液晶屏幕图像的自动分割分区,分析分区图像子小区块的图像数据,运用深度融合图像算法,产出控制环境光输出的RGB数据。采用LED驱动芯片TLC5971串联连接,来控制对应分区的LED灯条显示。由主控制器通过SPI通信将分区的图像RGB数据传送给TLC5971控制LED灯条实时显示画面颜色,达到液晶屏幕的画面延伸。

In order to solve the problems of extending the display effect of the LCD image through the LED light bar and synchronizing the display of screen color of LED light bar in real time,an ambient light control technology scheme based on SPI bus is proposed.The software algorithm is used to automatically partition the LCD image,analyze the image data of the subblock of the partition image,and a deep fusion image algorithm is used to produce RGB data that controls ambient light.The LED driver chip TLC5971 is cascading connection for controlling the LED bar display of the corresponding partition.The main controller transmits the RGB data of the partitioned image to TLC5971 through SPI bus to control the LED light bar to display the screen color in real time,so as to achieve the LCD screen extension.
