摘要
提出一种新型LED智能玻璃显示驱动器。该驱动器基于脉冲宽度调制的原理,通过驱动器中的特殊驱动芯片,将输入的串行视频数据转换为多路并行的灰度控制数据,再经过FPC软板驱动LED智能玻璃显示屏显示,实现每帧数据的全周期、4 096阶灰度级显示,多个驱动器可以进行级联,从而实现多个LED智能玻璃显示屏级联显示,进而增大显示画面,同时该驱动器还具有重量轻,体积、价格适中等优点,所驱动的LED智能玻璃显示屏各像素点色彩明亮、显示稳定,可被广泛运用于室内外LED智能玻璃显示驱动。
A new type of LED smart glass display driver was proposed. This driver was based on the principle of pulse width modulation. The special driver chip in the driver converted the input serial video data into multi-channel parallel grayscale control data,and then drove the LED smart glass display through the FPC soft board to realize the full cycle of each frame of data and 4 096 levels of grayscale multi-level display. Multiple drivers could be cascaded,so that multiple LED smart glass displays could be cascaded to increase the display screen. At the same time,the driver also could have the advantages of light weight,moderate volume and price. Each pixel of the screen has bright colors and stable display,and could be widely used in indoor and outdoor LED smart glass display.
