Product Description:
The CH400WV22C-CTB is a high-performance 3.97-inch IPS TFT LCD
module crafted by Chenghao Optoelectronic. Boasting a resolution of
480*800 dots, it delivers sharp and detailed visuals with 16
million colors, ensuring vivid and true-to-life image reproduction.
The IPS display technology offers an impressive 85/85/85/85 viewing
angle from all directions, eliminating color distortion and
providing consistent visibility.
| With a contrast ratio of 800 and a brightness of 600 cd/m², this
module performs exceptionally well even in bright environments. It
features a MIPI interface and a 25-pin FPC, enabling stable and
efficient data transmission. The capacitive touch function comes as
standard, with options to switch to resistive touch or no touch
based on specific requirements. |

| Chenghao Optoelectronic provides extensive customization services,
including FPC shape and pin number adjustments, interface
modifications (SPI, MCU, RGB, etc.), brightness tuning (300-1500
cd/m²), operating temperature adaptation (-45~+90℃), glass cover
customization, anti-glare treatment, and anti-electromagnetic
interference solutions, catering to diverse project needs. |
Features:
(1)Exceptional Full-View Performance: Built with IPS display technology, the CH400WV22C-CTB offers a
uniform viewing angle of 85/85/85/85 across all four orientations.
Unlike traditional display modules that suffer from color fading or
contrast loss when viewed off-center, this module maintains vivid
color accuracy and sharp image details from any perspective. It
effectively meets the demand for clear visibility in scenarios
where the observation direction is variable or multi-angle viewing
is required.
(2)Reliable Wide-Temperature Operation: This module is designed to withstand extreme temperature
conditions, featuring an operating temperature range of -20°C to
+70°C and a storage temperature range of -30°C to +80°C. Its robust
thermal stability ensures consistent performance without functional
degradation, whether deployed in cold outdoor environments or
high-temperature industrial settings. This wide-temperature
adaptability enhances its versatility and reliability in diverse
application scenarios.
(3)Stable MIPI Interface Configuration: Equipped with a MIPI interface and a 25-pin FPC, the
CH400WV22C-CTB enables efficient and stable data transmission. The
MIPI interface, a widely recognized standard in display technology,
ensures low signal interference and high communication efficiency,
facilitating seamless integration with various control units. The
25-pin FPC design optimizes connection reliability and mechanical
flexibility, simplifying the assembly process and improving the
module’s adaptability to different installation requirements.
