The AUO B173HAN04.3 is a high-quality 17.3 inch TFT-LCD display designed for use in laptops. Its active area measures 381.888(H)×214.812(V) mm, with an outline dimension of 389.89(H)×238.31(V) ×3.5(D) mm. The panel features a pixel format of 1920(RGB)×1080, resulting in a crisp and clear full high definition (FHD) display with a pixel density of 127 pixels per inch (PPI).

This panel uses an a-Si (amorphous silicon) TFT-LCD technology with an RGB vertical stripe configuration. It offers a high contrast ratio of 800:1 (Typ.) (TM) and a luminance of 300 cd/m² (Typ.). The display has a symmetrical viewing direction with a response time of 25 (Typ.)(Tr+Td), and a viewing angle of 85/85/85/85 (Typ.)(CR≥10).

The B173HAN04.3 supports 16.7 million colors with 100% sRGB color gamut, resulting in a vibrant and accurate color display. It also features an antiglare, hard coating (3H) treatment, which reduces the amount of glare and reflection on the screen, making it easier to view in brightly lit environments.

The panel uses an AHVA (Advanced Hyper-Viewing Angle) technology, which is a type of IPS (In-Plane Switching) panel that offers wide viewing angles and excellent color accuracy. It is a normally black, transmissive display that uses a WLED (White Light Emitting Diode) backlight with a rated lifespan of 15,000 hours, along with an integrated LED driver.

The display is designed in a flat form style with a PCBA flat thickness of T3.4~4.0mm, making it easy to integrate into laptops. It also comes with a 30-pin eDP (embedded DisplayPort) interface that supports eDP 1.3 with 2 lanes.

The B173HAN04.3 operates at a frame rate of 60Hz and does not come with a touch panel. It has a power supply voltage of 3.3V (Typ.) and is rated for an operating temperature range of 0 ~ 50 °C and a storage temperature range of -20 ~ 60 °C.
