dot matrix OLED monochrome character, graphic display module. Modules built 64 × 64 display data RAM, which corresponds to each data point on a bright OLED screen, the dark state; its interface circuit and operating instructions Lcd display modules simple, with 8-bit parallel data interface, read and write timing adaptation 6800 series timing can be directly connected to the 8-bit microprocessor; while Intel 8080 MCU timing needs to be connected with the timing of the conversion (OLED display principle).
VGS12864E display module display is 128, 64 lines, 64 lines using a line driver outputs and two columns of the drive controller, where each piece of column driver 64 outputs. Line driver and the MCU does not matter, as long as the Serial display modules power can be generated to provide the drive signal and the synchronous signal, the external signal module only on the column drivers. Column driver built 64 × 64-bit display memory, RAM is divided into 8, page 8 lines; each pixel on the display state of the display data memory correspondence you display data memory directly as a graphical display of the drive signal , "1" shows "0" is not displayed. Figure 1 is a block diagram of a logic circuit interface module.
Instruction modules and LCD driver HD61202 compatible controller, a total of seven instructions. Not described in detail here, as listed in Table 2 only instruction list. Among them, the state is set to show the first two instructions, the rest of the class to read and write commands.
lcd module displays screen splicing present the main application areas include security, command centers, entertainment industry, company presentations, advertising, media, exhibition center, electricity, education and so on. Advantages of lcd -screen high-resolution, high-brightness, high color saturation, flexible tiled display combinations, environmental health, long life, low maintenance costs, viewing angle, low power consumption, low heat, affordable .
