BLC2041-BL-USB is a display module used to provide instant visual feedback for industrial and consumer applications. It is part of the LCD, OLED character and numeric display family. The module is composed of a high-density polyethylene (HDPE), ultra slim form factor, single featured and robust LCD. It utilizes a fully integrated, reflector- based technology developed to ensure that the integrated LCD display module is readable even under the most demanding environment conditions.

The BLC2041-BL-USB possesses a contrast ratio of 500:1 and a pixel spot size of only 0,1366mm², making it an ideal Display Module solution for applications where space, power and contrast are limited. Further, it offers excellent colour saturation and true colour reproduction that makes it a top choice for applications such as medical imaging, gaming applications and multimedia displays.

The working principle of the BLC2041-BL-USB is based on a backlight illumination and liquid crystal display (LCD) technology. This combination offers improved contrast, stable imaging and excellent readability. The backlight is connected to a single source in such a manner as to provide uniform illumination across the display. This is achieved through a reflector mechanism that reflects the light in a constant angle to create similar illumination levels in the entire display.

The LCD used in the module is composed of two glass plates that are driven by electric fields. In between these two plates exists the liquid crystals. Depending on the polarization of the electric fields, the liquid crystals form a variety of different patterns and angles. When the voltage is on, the liquid crystals become twisted and when off, they become relaxed. This results in the light passing through the LCD and reaching the user’s eyes with varied intensity, thus creating the image.

The application fields most commonly associated with the BLC2041-BL-USB module include handheld consumer electronics and industrial controls. By combining the LCD and backlight-based technologies, the module is an excellent solution for projecting information in a reliable and consistent fashion. From consumer level applications such as music players and mobile phones, to industrial applications such as controlling machines and equipment, the BLC2041-BL-USB module has proven itself to be a reliable and efficient display module choice.
