ULCD-43 is an advanced Flexible TFT display module developed by Newhaven Display International. This module offers high graphics resolution, multiple source input signal compatibility, and wide temperature range driving capability, to meet the strong demand for industrial-grade display quality and performance. The ULCD-43 provides the ultimate in both affordability and user flexibility.
The ULCD-43 display module is designed to meet both the rugged and demanding requirements of industrial applications, while providing unparalleled performance in a compact form factor. It features a 4.3 inch TFT LCD with a resolution of 320 x 240 pixels and a module size of 78.4 x 60 mm, making it an ideal choice for space-constrained applications. This high-resolution display also supports multiple types of input signals, including RGB, Video, TTL, and LVDS.
In addition, the ULCD-43 is engineered for superior durability, with a wide operating temperature range from -20°C to 70°C and built-in EMI shielding for protection from electrical interference. This allows for reliable operation in harsher industrial conditions, so you can be sure to get a robust and reliable product. To ensure optimal image quality, the ULCD-43 has a brightness of 300 cd/m2, with a wide angle of visibility of 180° both horizontally and vertically.
To make the ULCD-43 even more user-friendly, it comes with an on-board resistive touch screen controller pre-installed. This allows users to easily and quickly access their data, control the display, navigate through their applications, and more. The ULCD-43 also supports multiple communication protocols, including USB, SPI and I2C, which further simplifies the development process.
The ULCD-43 is an excellent choice for a wide range of applications, from point-of-sale systems to data logging and monitoring equipment. Thanks to its superior display performance, multiple input signal compatibility, and robust design, the ULCD-43 is the ideal solution for applications requiring reliable, high-quality displays.
The ULCD-43 comes with a wide range of features, including a full set of control functions, that make it easy to integrate into any application. Its Working Principle is fairly simple and it starts with the LCD’s display mechanics. The ULCD-43 is built with a TFT-CCFL (Thin Film Transistor-Cold Cathode Fluorescent Lamp) LCD panel which utilises transistors and capacitors on the display screen to control and regulate the display of each pixel on the screen.
The display is powered by the on-board inverter unit, which supports both a 12V power supply for the CCFL backlight and a 5V supply for the display unit. The 5V supply provides electricity to the logic board which controls the active transistor elements on the LCD’s display elements. These elements open and close based on the logic signals from the logic board and the active elements on the LCD will then display specific pixels.
The ULCD-43 is designed with an SPI control interface, and the user can change the operation of the display via the SPI signals. The SPI protocol is an efficient communication interface which requires only four lines of transmission, and it is easy to implement and use. The SPI uses the Software SPI algorithm, which keeps the display’s configuration details in its memory and only writes the transmit data of the chip and display module as needed.
Overall, the ULCD-43 is an advanced display module, designed to meet the demanding requirements of industrial applications. Its high-resolution display, compatibility with multiple input signals, and wide operating temperature range make it the ideal choice for applications that demand a robust and reliable display. Thanks to its pre-installed on-board resistive touch screen controller and the SPI control interface, it is also highly user-friendly and easy to implement.
