5 inch High Brightness Screen IPS ST7701S

Product Overview

This 5.0-inch industrial-grade High Brightness Screen TFT LCD module (model: TFT-H050A11FWIST5C20), launched by HOTHMI, features a normally black IPS panel with a resolution of 480×854 pixels. It supports U80/D80/R80/L80 ultra-wide viewing angles and delivers NTSC 70% color gamut, paired with 500±100 cd/m² high brightness to ensure clear and vivid images under various lighting conditions.

The TFT section is driven by the ST7701S driver IC, with default MIPI 1L/2L interface; the touch section employs the GT911 chip with IIC interface for responsive and smooth touch performance. The module boasts a compact and robust structure, with overall dimensions of 68.50×133.00×4.20mm, utilizing high-quality 3M tape and OCA for multi-layer optical bonding, and includes a steel plate reinforcement for grounding. It operates with flexible supply voltages (VDD/VCI at 3.3V±0.3V, IOVCC supporting 1.7~3.3V), and the backlight runs stably at Vf=19.0±2.0V, If=40mA.

Furthermore, it offers excellent environmental tolerance, with a wide operating temperature range of -20℃ to +70℃ (storage: -30℃ to +80℃), making it an ideal choice for demanding applications such as IoT smart terminals, industrial automation instruments, and portable handheld devices.

High Brightness Screen Key Advantages

Superior Sunlight Readability with High Brightness

As the defining feature of this module, the High Brightness Screen capability is fully realized at the hardware level. Under constant current testing, the module delivers a stable industrial-grade brightness of 500±100 cd/m². This high-luminance design significantly enhances contrast and visual impact, ensuring clear content visibility even in bright outdoor environments.

IPS Full-Viewing-Angle Performance

The display adopts an advanced normally black IPS technology panel, offering U80/D80/R80/L80 full viewing angles. This means that operators can view the screen from any tilt direction—top, bottom, left, or right—while maintaining true color reproduction without distortion.

5-Point Industrial Capacitive Touch

Equipped with the GT911 touch driver IC, the module achieves high-speed touch communication via the IIC standard interface. The total CTP assembly thickness is 1.5mm, utilizing a double-layer OCA optical adhesive full-lamination process that eliminates air gaps between the touch layer and the TFT layer. This enhances light transmittance, reduces ambient light reflection, and fully exploits the high-brightness display effect. The screen natively supports 5-point simultaneous capacitive touch and multi-touch gesture recognition, with fast response times suited for routine industrial equipment operations.

Pin Configuration (TFT and CTP Interface Definitions)

This module features a split FPC cable design that integrates both TFT signal and capacitive touch panel (CTP) interfaces into a 20-pin flexible flat cable. The pin arrangement and signal definitions are detailed in the following table:

Industry Application Scenarios

Leveraging its remarkable High Brightness Screen sunlight-readable technology, wide-temperature operation (-20℃ to +70℃), and robust anti-interference architecture, the TFT-H050A11FWIST5C20 is widely deployed across various smart application fields:

• IoT Smart Terminals & Smart Home: Ideal as a core component for wall-mounted smart gateways, high-end video intercom panels, intelligent ventilation control centers, and EV charging station HMI interfaces.
• Industrial Automation & Power Equipment: Perfectly suited for embedded industrial PCs, CNC machine control panels, smart power inspection instruments, and substation monitoring terminals. The grounded steel plate reinforcement effectively handles high-frequency surges and electromagnetic interference in industrial environments.
• Handheld Electronic Testing Devices: With 500 cd/m² high-brightness output, it is an excellent choice for outdoor portable gas detectors, infrared thermal imagers, surveying instruments, and medical handheld diagnostic terminals.
• Automotive & Intelligent Transportation: Applicable for smart instrument clusters on two-wheeled electric vehicles, onboard displays for heavy engineering machinery, and localized passenger information screens in rail transit systems.

Technical Q&A of High Brightness Screen

Q: What is a High Brightness Screen? Can this 5.0-inch display be clearly viewed under direct sunlight?

A:A High Brightness Screen refers to a liquid crystal display that achieves significantly higher luminous intensity than conventional indoor screens, through optimized backlight module design, enhanced LED luminous efficiency, and the addition of brightness enhancement films. This TFT-H050A11FWIST5C20 model delivers a tested brightness of 500±100 cd/m². Combined with the high contrast ratio of the IPS full-view panel and OCA optical full-lamination technology that minimizes reflectance, the screen remains sharp and legible even under harsh outdoor sunlight. It fully meets the sunlight-readability requirements for outdoor or semi-outdoor equipment applications.
