Title: Image data transmitting method
Inventor: SHIYOURIN NOBORU
IPC: G02F1/133
Filed: 1990-08-27
Abstract: PURPOSE:To realize a graphic display on a large-screen LCD at a relatively low transmission rate by transmitting drawing data separately as color specification data and its run-length data on a drawing unit side, and converting them into the original drawing data and also converting the color specification data into data matching the color array of the LCD on a display unit side. CONSTITUTION:While a GC1a draws data on a #1VRAM1b, a #2VRAM1c operates for display processing and data stored in the #2VRAM1c are read out and led to an encoder 10c through a switching element SW2. A P/S10d reads data out in sequence, converts the data into serial data, and sends them out. In the display unit 20, an S/P2a converts the sent serial data into parallel data, which are led to a decoder 20b, thereby outputting a write signal to a frame memory 20d. An LUT20c converts the color specification data into the data matching the color array of the LCD.
