Display Modules - LCD, OLED, Graphic

GEN4-ULCD-32D-AR is an LCD module specifically designed and manufactured to meet the demands of many applications. The LCD module is characterized by a backlit LCD display, four on-board buttons, moderate power and high contrast with a bright, uniform field of vision squared by pixel.

The module is built with 4” diagonal display size, with a resolution of 320x240 pixels and landscape aspect ratio. It offers decent brightness of 200cd and a contrast ratio of 400:1. Additionally, the module is equipped with high-quality TFT and resistive touchscreen.

Application Fields

The GEN4-ULCD-32D-AR LCD module is suitable for a vast range of applications. It is suitable for medical applications where a low power consumption and a high contrast ratio are required. It is also used in the gaming and industrial industry, where the combination of good features partially compensates the high cost of the module. The module is highly suitable for any application that needs a resistive touchscreen in combination with a powerful LCD display in moderate power consumption.

Working Principle

The main component of the GEN4-ULCD-32D-AR module is the liquid crystal display (LCD). It is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. The function of the LCD display is to control the pattern of the pixels. Each pixel is connected to one or more thin film transistors (TFT). These transistors control the electrical charges flowing through that particular segment of the LCD.

The LCD is also connected to an LED backlight, which gives the LCD panel its brightness. The LED backlight is in turn connected to a circuit board that produces the necessary electrical signals to control that backlight. Finally, the LCD panel is connected to the controller board, which receives signals from the user input, such as buttons or a stylus. The controller board converts these signals into ones that it can understand and then communicates with the LCD panel on how to display the data to the user.

In short, the GEN4-ULCD-32D-AR module uses liquid crystal display technology to provide the user with high contrast display with a bright, uniform field of vision squared by pixel. This combination of features allows for the module to be used in a variety of applications, from medical to industrial.
