The LQ084S3LG03 is a display module used in a variety of applications such as industrial automation, office automation, instrumentation and consumer electronics. It is a Liquid Crystal Display (LCD) module, consisting of an array of liquid crystal cells and a light source, typically a light-emitting diode (LED) backlight.

The module is composed of active and passive components. The active components include a negative voltage generator, voltage regulator, LCD driver and buffer circuit. The passive components are the LCD panel and LED backlight.

The module is equipped with a 20-pin FPC connector for easy connection to a microcontroller or video processor. With a 30-pin connector, LQ084S3LG03 can be used in portrait or landscape mode.

The module has a 106.2mm x 86.4mm display size including the illuminated area, and offers a 480 x 272 resolution. It has a transmittance brightness of 300 cd/m2 and a contrast ratio of 200:1.

The LQ084S3LG03 module has a wide operating temperature range of -20°C to +70°C. It is also resistant to moisture, shock and vibration.

The working principle of LQ084S3LG03 is simple: Polarization of the display is done by a voltage applied between the LCD (liquid crystal) and ITO (transparent conductive oxide) electrodes.

A polaroid filter is used to rotate the polarization plane to give the right contrast.The voltage applied to the pixel is varied, thereby changing the brightness of the pixel. The light source illuminates the LCD panel and the image is visible due to the scattering of colored polarized light.

The LQ084S3LG03 module is ideal for a variety of industrial and commercial applications such as measuring instruments and medical equipment. It is also suitable for high-resolution displays for in-vehicle systems and portable multimedia devices.

The LQ084S3LG03 display module can be used as an information display, vehicle information panel, human machine interface (HMI), and handheld device. It is well suited for in-vehicle navigation systems, music players, and other portable multimedia devices. It is also ideal for industrial instrumentation and control systems, medical devices, and home appliances.

The LQ084S3LG03 module is a versatile tool in display application. With its wide operating temperature range, high resolution, and transmittance brightness, it is sure to meet the demands of many industrial and consumer applications.
