Product Introduction


4 Inch 720x720 Wide Temperature Display Overview
ET040HD20-KT is a 4-inch diagonal TFT-LCD display module designed for wide temperature industrial applications. It supports a resolution of 720×720 with a square aspect ratio of 1:1 (W:H) and utilizes a MIPI interface driven by the ST7703 controller for high-speed and stable signal transmission. The display features an active area of 71.928 (W) × 71.928 (H) mm and an outline dimension of 84 (W) × 85.99 (H) × 3.76 (D) mm. It delivers a brightness of 650 cd/m², ensuring reliable visibility under various lighting conditions. With a free viewing angle (L/R/U/D), it provides consistent image quality from multiple directions. The module integrates a capacitive touch panel for enhanced user interaction and is engineered for dependable operation within a wide temperature range of -30°C to 80°C.
