LQ042T5DZ13K Application Field and Working Principle

Display Modules - LCD, OLED, Graphic

The type-LQ042T5DZ13K TFT LCD is an active-matrix liquid crystal diplay (AMLCD) display module resolution of 640 x 480 with a diagonal of 4.2" and an aspect ratio of 4:3. This display module has 262K colors, a brightness of 300 Nits, and an operating temperature range of 0 - 70 °C. The LQ042T5DZ13K is composed of a monochrome color TFT LCD panel, a signal interface, a power source, LED backlight, LED control circuit and a mechanical structure.

Application

The LQ042T5DZ13K is an ideal solution for industrial and commercial applications requiring a low-cost, high-performance display. This display can be used for a variety of applications such as OEM products, car and kiosks. The LQ042T5DZ13K\'s excellent readability in a variety of light conditions and its low power consumption makes it suitable for a wide range of uses, including consumer, automotive, industrial and medical applications.

Working Principle

The LQ042T5DZ13K display module operates using an active-matrix LCD technology. This technology works by placing an array of thin-film transistors (TFT) on the substrate of the LCD display. These TFTs are connected to the addressing lines and electrodes of the LCD, with the help of the signal interface and power source. The TFTs then act as a driving device to control the functioning of the LCD. The two electrodes of the LCD display (commonly referred to as the row and column electrodes) are connected to the TFT array. When a signal is applied to the electrodes, the LCD will switch between being open (visible) and being closed (off). This cycle will result in the display of pixels on the LCD display. This process operates on the basis of the electric field created between the two electrodes and will result in the display of the pixels in the intended pattern. The display brightness of the LCD display is determined by the level of electricity applied to the LCD electrodes. The backlight circuit will determine the brightness of the pixels by adjusting the amount of electric current supplied to the backlight LEDs. Since the process of electricity supply and working conditions are controlled and regulated by the signal interface and power source, the LQ042T5DZ13K display module is able to reduce power consumption and provide excellent display performance.

Conclusion

The LQ042T5DZ13K is an active-matrix liquid crystal diplay (AMLCD) display module with a resolution of 640 x 480 and an aspect ratio of 4:3, making it a suitable solution for industrial and commercial applications requiring a low-cost, high-performance display. This display works on the basis of an active-matrix LCD technology and is able to reduce power consumption as well as produce excellent readability in a variety of light conditions.
