Tall Portrait 5 inch Display 480×854 Pixels ST7701S Controller

Description

ER-TFT050A2-9 is a 5-inch IPS TFT LCD display​ with a tall portrait format of 480×854 pixels​ (61.63×109.65 mm active area, 62.63×110.65 mm visual area), aimed at handheld instruments, intercom panels, and embedded HMI where a wide 4:3 or 16:9 screen will not fit. The IPS cell gives a true 80°/80°/80°/80°​ viewing cone, 65K/262K/16.7M​ color depth, a 500:1​ typical contrast ratio, and 410 cd/m²​ brightness, so menus, maps, and vertical lists stay vivid from any mounting angle.

ER-TFT050A2-9 integrates the ST7701S​ controller in COG packaging. It is initialized over a 3-wire SPI​ bus (SCL, SDA, /CS, /RESET) and then streams pixel data over a 24-bit RGB parallel interface​ (DB0–DB23, DCLK, HSYNC, VSYNC, DE) at higher throughput — the same sequencing pattern as the ER-TFT040-3 family. Logic runs at 2.5–3.3 V typ. 2.8 V​ (absolute max 3.6 V on VDD), with a 20 ms typical response time. The 12-chip LED backlight (6 serial × 2 parallel groups) needs 18 V typ. / 19.2 V max @ 30–40 mA​ and is rated for 30,000 hours at 25 ℃. No touch is mounted by default.

ER-TFT050A2-9 is offered with an optional capacitive touch panel (ER-TPC050A2-9)​ carrying its own I²C controller on a separate 6-pin FPC (GND, RST, INT, SDA, SCL, VCC 2.8–3.3 V) for finger and multi-touch input. We provide ST7701S init code, RGB timing examples, and demo projects for STM32 (LTDC/RGB peripherals), i.MX/Rockchip/Pi Linux SBCs via DRM panel drivers, and ESP32-S3 (8-bit/16-bit parallel with SPI boot)​ on buydisplay.com. Because the panel is RGB-primary, it targets MCUs/SBCs with a parallel LCD peripheral rather than low-pin-count Arduinos.

Rated for −20~+70 ℃​ operating and −30~+80 ℃​ storage, ER-TFT050A2-9 is built for indoor enclosures. It is not sunlight-readable, so it is intended for backlit cabinets and console fronts, not direct outdoor sun. As with all TFT panels, avoid a fixed image longer than 2 hours to prevent temporary image sticking (reversible via an all-black screen-saver period).

That is suitable for a wide range of applications, including industrial control consoles, smart-home wall panels, portable medical instruments, intercom and security keypads, POS side displays, and any Linux/MCU HMI project needing a tall 5-inch IPS color screen with RGB throughput and optional capacitive touch.

For users of the 8051 microcontroller, we have carefully prepared a comprehensive interfacing document, demonstration code, and an 8051 development board specifically tailored for this display.
