B156ZAN03.4 Overview
The B156ZAN03.4 is a 15.6-inch LTPS TFT-LCD display panel from AUO. It utilizes color active-matrix display technology and consists of a TFT LCD panel, driver circuitry, and an LED backlight system. The panel features a 3840 × 2160 UHD (4K) resolution, a 16:9 aspect ratio, and supports 16.7 million colors (RGB 8-bit), delivering sharp image quality and accurate color reproduction for high-resolution display applications.
The B156ZAN03.4 uses an eDP (Embedded DisplayPort) interface for signal transmission, providing high-speed data communication and broad system compatibility. It is widely used in notebook computers, mobile workstations, and industrial display terminals that require detailed visuals and reliable display performance.
B156ZAN03.4 Structure and Principle
The B156ZAN03.4 TFT-LCD module integrates a 40-pin eDP (Embedded DisplayPort) high-speed signal interface, driver circuitry, and a WLED backlight unit.
In terms of display principle, it adopts the advanced AHVA (Advanced Hyper-Viewing Angle, an IPS-type wide viewing technology) mode. Digital signals from the main controller precisely regulate the electric field applied to the TFT electrodes, thereby controlling the deflection angle of liquid crystal molecules through birefringence modulation.
Combined with a high color-gamut WLED backlight and polarizer system, the module achieves sub-pixel-level and microsecond-scale control of light transmittance. As a result, it delivers image output with up to 100% Adobe RGB color coverage.
