COG LCD Display

Then how to use control, through theof 13 Interface Control SSD1303 driver thereby controlling the OLED display.  is the chip select signal, then low when to communicate with the driver is reset enable end, when the then low, all control registers are set to the factory default state, while image register is cleared; for the data  command 20x4 lcd select signal;  respectively write and read select signal when  is low, effective in its falling edge read and write. By changing the   three interface level, single-chip control of OLED has four states, can be displayed in Table 1.
read and write timing

Just follow VGG12864G timing waveforms to read and write, to complete the OLED display. However, the fight sequence through software programming, a lot of time to take into account the parameters, there is a certain degree of difficulty. To make it easier for data and commands to write smoothly, we take a different approach. Shown in Figure 1, the  and respectively, then the and  namely P0.7 and P0.6. When you define a pointer COG LCD Display type xdata type in the C programming language, which is pointing to off-chip memory through a pointer to an assignment outside access off-chip data storage area when accessing off-chip memory,  and will read and write automatically becomes low, while P3 port for the data bus, a non-multiplexed mode, the high use of the address bus 8 port P1, P2 port using low 8; under way multiplexed address bus high eight still using P1 port, low 8 and multiplexed data bus port P3, P2 port will not be affected. So the best way to set multiplexing (EMIOCF.4 = 0), P2 port can be used unless the output port, the freedom to control the Although no address bus, but when accessing off-chip memory address lines are used, so still avoid. The results of the timing waveform diagram shown in Figure 3. As long as  is low, the falling edge of  write (read) data or commands to read and write effectively complete the work.

OLED display modules

The OLED display changes the way we think about television. With its ability to switch off individual pixels, lcd display achieves deeper blacks and an infinite contrast ratio. In addition, it has a response time that is over 100 times quicker than its nearest competitors, though it stands at only half their weight. Plus, our COG LCD Display is as thin as three credit cards, which is  innovation and design at its best.
Also, since our OLED displays are self-illuminating screens, they use far less power than any of its competitors. lcddisplaymodules means  OLED displays are some of the most eco-friendly televisions available.

OLED Display street lighting to minimize electricity.

Meanwhile, the sea still on the street lights on the implementation of energy-saving lighting control, shut down Gordon Road, Red City Lake Road, Xiuying Avenue, 110 road vehicle Road Low Temperature Display Central African arms side street lamps light, peace Avenue, Century Avenue , five-arm street light 119 Haidian Road and other roads in the implementation halved after 23:00 midnight lights, street lamps on the arm Hongmian East, West, Wing Wan Road Phase II, 31 roads and other long Rd implementation halve the whole night lights, street lighting to minimize electricity.

"We take energy-saving lighting control measures, hoping to get the public to understand." Haikou Municipal Engineering maintenance company official said, halve lighting energy-saving COG LCD Display measures are aimed primarily at smaller sections of nighttime traffic, the guarantor, the more traffic big downtown main road lighting properly. After taking this measure energy-saving effect is very obvious, such as purple Road area located Xiuying, all sections of the measures taken after every lamp lights, the monthly saving 2587.5 degrees, a year-saving amounted to 31,050 degrees. He urged people from saving electricity and other little things, love municipal facilities, to build a resource-saving and environment-friendly society.
