Product details
Overview
RK055HDMIPI4MA0 from Rocktech Displays Limited is a 5.5-inch capacitive touch TFT LCD module with 720×RGB×1280 resolution, MIPI DSI interface, IPS transmissive panel, and integrated RM68200 display controller and GT911 touch controller - designed for embedded human-machine interfaces requiring full viewing angle and high-contrast visual output.
For engineers reviewing the RK055HDMIPI4MA0 datasheet, RK055HDMIPI4MA0 pinout, RK055HDMIPI4MA0 application, or RK055HDMIPI4MA0 equivalent, key selection considerations include MIPI DSI lane count (4 data lanes + clock), dual power domains (VCC=3.3V, IOVCC=1.8V), backlight voltage (22.4V typ), CTP I²C interface (CTP_SDA/CTP_SCL), and mechanical envelope (79.24×133.96×3.90 mm).
Technical Context
This module integrates a transmissive IPS TFT LCD panel driven by the RM68200 all-in-one display controller, supporting MIPI DSI v1.2 with four high-speed data lanes and one differential clock pair. It delivers native 720×1280 RGB vertical stripe timing with 35 ms typical response time and 800:1 contrast ratio.
The capacitive touch subsystem uses the GT911 controller communicating via dedicated I²C bus (CTP_SDA/CTP_SCL) with interrupt-driven reporting (CTP_INT) and hardware reset (CTP_RST). Backlight is driven by constant-current LED string requiring 22.4 V at 40 mA, delivering 280 cd/m² luminance after CTP lamination.

Equivalent & Alternatives
The following parts are listed as comparable options for similar embedded display module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ED055XG2 (Epson) | Same 5.5", 720×1280, but uses LVDS interface and separate touch controller; no integrated MIPI DSI or CTP | Requires external LVDS transmitter and touch bridge IC - higher BOM count and layout complexity | Choose when legacy LVDS host interface exists and touch integration is handled separately |
| AT055TN12 (AUO) | 5.5", 720×1280 IPS panel only - no driver IC, no CTP, no backlight; requires full external timing and power management | Demands complete display subsystem design - not plug-and-play like RK055HDMIPI4MA0 | Choose only for highly customized designs where full control over timing, gamma, and backlight dimming is required |
Compared with ED055XG2 and AT055TN12, RK055HDMIPI4MA0 reduces system integration effort through single-cable MIPI DSI connectivity, factory-laminated CTP, and embedded RM68200/GT911 firmware - enabling faster qualification and lower validation risk in volume production.

FAQ
What interface does the RK055HDMIPI4MA0 use for display data transmission?
The RK055HDMIPI4MA0 uses a MIPI DSI interface compliant with v1.2, featuring four high-speed differential data lanes (MIPI_TDN0–MIPI_TDP3) and one differential clock pair (MIPI_TCN/MIPITCP). This allows direct connection to MIPI-capable application processors without level-shifting or protocol translation. The RK055HDMIPI4MA0 does not support parallel RGB, LVDS, or eDP interfaces.
Does the RK055HDMIPI4MA0 include a built-in touch controller, and what interface does it use?
Yes, the RK055HDMIPI4MA0 integrates the GT911 capacitive touch controller, accessible via a dedicated 1.8–3.3 V I²C bus using pins CTP_SDA and CTP_SCL. Touch events are reported through the CTP_INT pin, enabling interrupt-driven polling. The RK055HDMIPI4MA0 does not require external touch firmware loading - GT911 initialization is handled internally.
What are the power supply requirements for the RK055HDMIPI4MA0?
The RK055HDMIPI4MA0 requires three independent supplies: VDD 2.8 V for display logic, IOVCC 1.8 V for MIPI I/O, and VDD 3.3 V for CTP operation. Backlight is powered separately via LEDA/LEDK pins at 22.4 V (typical) with 40 mA constant current. All GND pins must be connected to a common low-impedance ground plane.
Is the RK055HDMIPI4MA0 suitable for outdoor or high-brightness environments?
The RK055HDMIPI4MA0 has a typical luminance of 280 cd/m² after CTP lamination, which is appropriate for indoor and shaded outdoor use but not direct sunlight. It does not include optical bonding, anti-reflective coating, or auto-brightness adjustment. For high-ambient-light applications, external brightness boosting or optical enhancement would be required beyond the RK055HDMIPI4MA0's native capability.
What mechanical mounting provisions does the RK055HDMIPI4MA0 provide?
The RK055HDMIPI4MA0 features four corner mounting holes compatible with M2 screws, positioned to align with standard 5.5-inch display cutouts. Its rigid-flex construction and 3.90 mm total thickness allow secure front- or rear-mounting without torsional stress. The ZIF connector is oriented along the short edge (79.24 mm side), and cable routing must avoid bending radius <5 mm to prevent flex fatigue.
