oled graphic display Chongming Island, the Director of the estuary
the curved screen a total area of 120 square meters. Below the screen body using the latest LED waterlines shaped screen, showing the effect is like water, like, realistic effect. The implementation of the project, Lanshuo technician breakthrough in the shortest possible time multi-channel LED display technical difficulties - the courage to challenge, less than 15 working days to complete the project, which is the Shanghai World Expo in Shanghai, following Lanshuo Bamboo and Rattan after another major museum projects in Shanghai. This marks the Shanghai oled graphic COG LCD Display display Urban Planning Lanshuo Hall for each project tailored ripe. Currently, Shanghai Lanshuo now covers the northeastern provinces, the Northwest region, as well as central and eastern regions. Including the Shanghai Urban Planning Exhibition Hall Chongming, Shanghai North Industrial Park Planning Exhibition Hall, Fujian Longyan Urban Planning Exhibition Hall, Wenling, Zhejiang Urban Planning Exhibition Hall, Jiangxi Shangrao Urban Planning Graphic OLED Display Exhibition Hall, Zhuzhou, Hunan Urban Planning Exhibition Hall and other Planning Exhibition Hall ! Shanghai blue-seok as a mature LED electronic display manufacturers, not only has advanced equipment and a wide variety of LED display products, designed to provide customers with a more suitable environment LED display.Chongming Island, the Director of the estuary, is the third largest island in China, known as the "gateway to the Yangtze River, the East China Sea Chou" is the world's largest alluvial island estuary, the world's largest sand island. Chongming Island into land over 1,300 years of history, the existing area of 1,041.21 square kilometers, an altitude of 3.5 meters to 4.5 meters. The island is flat, fertile land, lush forests, abundant resources, a well-known land of plenty.

hope oled display module future products to join management clip function.
buttons are located on the bottom side of the border are lower, the keys feel quite satisfactory, the menu system is relatively new (Click here to see M2336 menu design). It is worth mentioning that, GreatWall M2336 back vents using irregular design, wave-like design allows us to feel the touch of refreshing summer.
It is gratifying that comfort GreatWall M2336 pitch adjustment is good, moderate intensity, no creak Lcd display modules sound, indicating that the quality aspect compared to a few years ago still oled display module have progress. Interface, this product is equipped with dual DVI and D-Sub interface, taking into account the market price of 1099 yuan, and failed with HDMI interface is understandable.
The same polished base material, and the body go, a little pity is that this product does not provide a reasonable clip the back of functional design, hope GreatWall future oled display Serial display modules module products to join management clip function.
Performance test papers (picture can click to enlarge view)
Test environment: 100% brightness, 75% contrast, and color temperature of warm colors (the default), due to the effect of DC shooting distance using real visual effects still not a small gap, so the following comparison shows the picture is only for reference, not as a test in conclusion. However, we will test the true feelings tell you.
Brightness uniformity

designed to provide customers with a more suitable environment oled display module
Recent Lanshuo planning Chongming Island, Shanghai Science and Technology Museum to build indoor giant curved screen and high-definition LED screen LED waterlines are now completed, the curved screen a total area of 120 square meters. Below the screen body using the latest oled display module shaped screen, showing the effect is like water, like, realistic effect. The implementation of the project, Lanshuo technician breakthrough in the shortest possible time multi-channel LED display technical difficulties - the courage to challenge, less than 15 working Lcd display modules days to complete the project, which is the Shanghai World Expo in Shanghai, following Lanshuo Bamboo and Rattan after another major museum projects in Shanghai. This marks the Shanghai Urban Planning Lanshuo Hall for each project tailored ripe. Currently, Shanghai Lanshuo now covers the oled display module northeastern provinces, the Northwest region, as well as central and eastern regions. Including the Shanghai Urban Planning Serial display modules Exhibition Hall Chongming, Shanghai North Industrial Park Planning Exhibition Hall, Fujian Longyan Urban Planning Exhibition Hall, Wenling, Zhejiang Urban Planning Exhibition Hall, Jiangxi Shangrao Urban Planning Exhibition Hall, Zhuzhou, Hunan Urban Planning Exhibition Hall and other Planning Exhibition Hall ! Shanghai blue-seok as a mature LED electronic display manufacturers, not only has advanced equipment and a wide variety of LED display products, designed to provide customers with a more suitable environment LED display.

one is the direct access oled display module, the other is indirect access.
Display Module with Cygnal microcontroller hardware interface design
VGS12864E interface connection in two ways: one is the direct access mode, the other is indirect access. Either way, you want to access the module must first read the contents of the status register to determine the "busy" flag can be accessed when not busy. Direct Graphic lcd modules access method is a module interface as a memory or I / O devices directly oled display module
linked to the MCU bus, MCU to access memory or I / O device mode the module operation. Indirect access MCU module is operated via software simulation control timing. Here is indirect access interface design Cygnal C8051F020 MCU and VGS12864E of.
Cygnal C8051F020 is an American company launched a mixed-signal SoC-based 8-bit microcontroller, a highly integrated mixed-signal system-on-chip. It has a 100-pin TQFP package, low power Character LCD Display supply voltage of 2.7 ~ 3.3 V, all I / O, RST, JTAG pins are resistant to 5 V voltage; has high speed pipelined 8051-compatible CIP51 core structure (up to 25 MIPS). The MCU has a total of 64 P0 ~ P7 purpose I / O ports, each port pin can be configured as push-pull output or open-drain output. For VGS12864E, due to its operating voltage is 5 V, and C8051F020 operating voltage is 3.3 V, so the output C8051F020 better able to drive 5 V input OLED, the system requires additional configuration. In addition to the corresponding output port is set to "open drain", but also in the circuit will be connected to each port through a pull-up resistor on a 5 V power supply, so you can ensure C8051F020 logic "1" output can be raised to 5 V. The interface circuit shown in Figure 2.
