GEN4-ULCD-70D-SB-PI Datasheet/PDFDisplays are components that display information. Display modules have different display technologies. LCD, OLED, Graphic display modules are typical display modules with their own application fields and working principles. In this article, GEN4-ULCD-70D-SB-PI display module will be introduced in detail.
1. Overview of GEN4-ULCD-70D-SB-PI
The GEN4-ULCD-70D-SB-PI display module is a color LCD display module with a resolution of 640x480 pixels and a diagonal of 7.0 inches. It has an integrated touch panel and four keys. The module has serial ports, SPI, RGB16/18/24 buses, Interrupt and I²C interfaces. This display module uses transflective backlighting, which makes it suitable for outdoor applications. It requires a single 3.3V power supply and the power consumption is only 1W.
2. Application Field of GEN4-ULCD-70D-SB-PI
The GEN4-ULCD-70D-SB-PI is a color LCD display module, which is suitable for various applications. It is often used in SMT assembly line, robots, smart factories, elevators, etc. The integrated touch panel and four keys make it easy to control the display. Additionally, the transflective backlighting makes it suitable for outdoor applications or in dusty environments. It is also widely used in POS, healthcare, tourism, industrial control and other industries.
3. Working Principle of GEN4-ULCD-70D-SB-PI
The GEN4-ULCD-70D-SB-PI utilizes an LCD display panel with LED backlight. It consists of an LCD panel and a Backlight Driver Board (LDB). The LDB is used to drive the LED backlight and provide power to the LCD panel. The LCD panel consists of thin film transistors (TFTs), which are arranged in a matrix of pixels. The TFTs are used to switch the backlight out to display the necessary information. The information is transferred from the video signal to the LCD panel via the LVDS driver board. The LVDS driver board uses the LVDS protocol for data transfer. The touch panel is used as an input device to interact with the display. The touch panel uses the serial port for communicating with the system.
Conclusion
The GEN4-ULCD-70D-SB-PI is a color LCD display module with 640x480 resolution. It is suitable for various application fields due to its transflective backlighting and integrated keys & touch panel. It requires a single 3.3V power supply and the power consumption is only 1W. The internal working principle of GEN4-ULCD-70D-SB-PI is also introduced in this article.
