UEZGUI-1788-43WQS-BA Application Field and Working Principle

Introduction

UEZGUI-1788-43WQS-BA, belonging to the display modules - LCD, OLED, Graphic category, is a 4.3” 4-wire resistive single chip TFT module with a resolution of 480x272, a dot pitch of 0.0675 x 0.2025mm, a voltage of 3.3V and a controller of Epson/Hitachi. It supports up to 65K colors.

Application Field

UEZGUI-1788-43WQS-BA has a wide range of applications such as home appliance control, medical equipment control, industrial automation, educational measurement, multimedia electronic publications, vehicle navigation systems, point of sale systems testing instruments, hand-held terminals and so on.

Working Principle

The UEZGUI-1788-43WQS-BA display module works on the principle of propagation of an electrical signal along an LCD array. It contains an LCD panel, a backlight, and a controller. The display panel is the main component of an LCD. It is a combination of several layers that are responsible for the display of images. The two main layers are the color filter layer and a thin-film transistor array layer. The color filter layer is composed of several colors that when combined can create a wide range of colors. The thin-film transistor array layer consists of small transistors that control the voltage applied to certain pixels. At the bottom of the LCD panel is the backlight. This is usually made up of fluorescent or LED lamps, and assists in the lighting of the LCD panel. As the brightness decreases, the colors become more intense. The controller is a separate device that controls the interactions between the backlight and LCD panel. It also assists in signal processing tasks such as grinding, blending, scaling and other signal process. Finally, the UEZGUI-1788-43WQS-BA display module integrates the LCD panel, backlight and controller into a single device. It also includes other elements such as a viewing angle control and image stabilizer. In conclusion, the UEZGUI-1788-43WQS-BA display module utilizes the working principle of propagation of an electrical signal along an LCD array to display images. Its wide range of applications and its integration of the LCD panel, backlight and controller into a single device makes it a great choice for any project.
