UEZGUI-1788-70WVM-BA Application Field and Working Principle

The UEZGUI-1788-70WVM-BA embedded LCD module from the EUK embedded devices series is a versatile graphic display. It provides vivid color depth and a clear graphics display for a wide range of applications, ranging from industrial displays to multimedia displays. It is designed for flexibility and durability, and its small size makes it perfect for embedded projects.

The UEZGUI-1788-70WVM-BA is built around a 16-bit WQVGA TFT LCD panel. The panel has resolutions of 480 horizontal by 272 vertical pixels, and supports 256 shades of gray. It also has high brightness and a good contrast ratio of 164:1 (typical). There is also an adjustable backlight control, and a dual channel LVDS interface, with 24 bits (8-bits in each color).

The UEZGUI-1788-70WVM-BA has a number of convenient features to make it easy to use. It has four-button navigation for menu control, with integrated buttons for menu navigation and backlight adjustment. There are also six user accessible LEDs for indication and power. The module also supports optional touchscreens, as well as an audio amplifier and speaker, making it suitable for multimedia applications.

The module is powered by a low-power Texas Instruments EMIFV7 processor. This processor is capable of running at up to 120MHz frequencies, making it ideal for embedded application designs. For storage, the processor supports external NOR/NAND Flash memories, as well as DDR SDRAM for long-term data storage.

Working Principle

At the heart of the UEZGUI-1788-70WVM-BA is the TI EMIFV7 processor. This processor is the main controller of the display module, and is used to process display commands, control the LCD panel, and drive the touchpanel. The processor interfaces with an external NOR/NAND Flash memory for storing application programs and data. The module also contains an integrated power supply that powers the 6 LEDs and LCD panel.

The display commands sent to the processor are translated into display commands that are sent to the LCD panel. This includes instructions such as position, size, color and frame rate. The output is then sent to the LCD panel, which displays the required result. The display commands can also be sent to the optional touch panel, and the output is then used to process any touch panel events.

The UEZGUI-1788-70WVM-BA can also support audio playback through the integrated audio amplifier and speaker. This feature can be used to add audio support to display applications, such as multimedia or other audio-based applications.
