GTT38A-TPR-BLH-B0-H1-CT-V5 Application Field and Working Principle

The GTT38A-TPR-BLH-B0-H1-CT-V5 module is a special LCD display module designed for data acquisition and radiation sensing applications.

The GTT38A-TPR-BLH-B0-H1-CT-V5 module features an ultra-high-definition (UHD) display with an ultra-thin profile. It is a powerful 3.2" display with a resolution of 1320 x 800 pixels and a brightness of up to 1100 nits. The GTT38A-TPR-BLH-B0-H1-CT-V5 module also features an advanced dot matrix design for enhanced image detail.

Application field:

• Radiation sensing
• Data acquisition
• Hazardous area visualization
• Industrial automation
• Surveillance

Working Principle:

The GTT38A-TPR-BLH-B0-H1-CT-V5 module is a thin-film transistor (TFT) liquid crystal display (LCD) module. In an LCD display, liquid crystals tilted at an angle switch states between the bright polarizer and the dark polarizer; individual pixels are lit when desired by charges applied to micro-electrodes.

The brightness of the display is determined by a voltage applied to the liquid crystal layer. The GTT38A-TPR-BLH-B0-H1-CT-V5 module employs a technique called charge redistribution to achieve ultra-high brightness and contrast. In this technique, a thin, transparent film on the outside of the LCD panel is charged before the LCD panel is illuminated, allowing the light to be re-distributed for maximum brightness before it is viewed by the eye.

The GTT38A-TPR-BLH-B0-H1-CT-V5 also features an advanced backlight technology that allows the image to be visible in low light conditions, making it suitable for use in surveillance and hazardous area visualizations. The module has an integrated ambient light sensing functionality that can be used to adjust the display brightness accordingly, helping to save power and extend the system’s battery life.
