5 Inch IPS TFT LCD Module with Capacitive Touch - 900 cd/m² High Brightness SPI Display

Product Description

The CH500WV05B-CT-PA is a 5.0 inch IPS TFT LCD module featuring an integrated capacitive touch panel and an onboard EVE2 graphics controller. With a resolution of 800 x 480 WVGA pixels and an ultra-high brightness of 900 cd/m², this display delivers exceptional image clarity and sunlight readability, making it ideal for outdoor kiosks, medical devices, and industrial HMI applications where strong ambient light is present. The advanced IPS technology provides a wide viewing angle of 80/80/80/80 degrees, ensuring consistent color reproduction and image quality from virtually any direction without color shift or inversion. Equipped with a standard SPI interface that also supports D-SPI and Q-SPI modes, this module offers flexible and high-speed data communication while minimizing the number of required I/O pins on the host controller. The display operates in transmissive mode with normally black technology and features an anti-glare surface treatment to effectively minimize reflections from ambient light sources. The integrated capacitive touch panel with a durable glass lens cover provides responsive, accurate, and multi-touch input capability. A built-in PCB driver board is attached to the back of the module, incorporating an EVE2 embedded video engine that handles display rendering, touch processing, and audio output, significantly reducing the burden on the host microcontroller and simplifying system design. With dual connection options including a 20-pin IDC box header and a 20-pin FFC connector, this module offers versatile integration possibilities for a wide range of embedded applications across industrial, medical, and smart home markets.

Product Features

• Ultra-High Brightness for Sunlight Readability: With a typical brightness of 900 cd/m², the display remains clearly visible even under direct sunlight. This makes it an excellent choice for outdoor kiosks, marine electronics, garden equipment interfaces, and any application where the display must compete with strong ambient light. The high-luminance LED backlight circuit, driven by a dedicated high-efficiency LED driver with PWM control, ensures consistent brightness while maintaining power efficiency.

• Integrated EVE2 Graphics Controller for Simplified System Design: The onboard * Embedded Video Engine (EVE2) integrates display control, touch management, and audio output into a single chip. This eliminates the need for a separate graphics controller or frame buffer, significantly reducing BOM cost, PCB space, and firmware development time. The EVE2 supports advanced graphics primitives, widget rendering, and audio playback, enabling rich human-machine interfaces with just a low-cost SPI-enabled microcontroller.

• Full Viewing Angle IPS Display Technology: The IPS (In-Plane Switching) panel delivers superior color performance with 80/80/80/80 degree viewing angles in all directions. Unlike standard TN panels, colors remain stable and accurate without inversion or significant brightness loss when viewed from extreme angles. This is particularly important for devices with wide or adjustable viewing positions, such as medical equipment, industrial control panels, and in-vehicle displays shared between driver and passenger.

• Dual Interface Connectivity for Flexible Integration: The module offers two independent connection options: a 20-pin 2x10 IDC box header with 2.54mm pitch and a 20-pin 1.0mm pitch top-contact FFC connector. This dual-interface design allows engineers to choose the most suitable connection method for their specific PCB layout and mechanical constraints. The flexible connectivity reduces the need for custom adapter boards and simplifies prototyping, production, and field maintenance.

The capacitive touch interface supports modern gesture-based interaction, and the high brightness ensures readability in both dark hallways and sunlit living rooms.

FAQ

Q: What is the typical application for the CH500WV05B-CT-PA module? A: This module is designed for industrial HMI, medical equipment, smart home control panels, outdoor kiosks, and any embedded system requiring a high-brightness color display with touch interface. Its integrated EVE2 graphics controller makes it particularly suitable for applications where reducing host processor load and simplifying hardware design are priorities.

Q: Does the module include the touch panel, or do I need to purchase it separately? A: The CH500WV05B-CT-PA comes with an integrated capacitive touch panel and a glass lens cover pre-assembled. No additional touch panel purchase is required. The touch controller is handled by the onboard EVE2 processor, so no external touch controller IC is needed.

Q: What microcontrollers or processors are compatible with the SPI interface? A: Any microcontroller with an SPI interface can communicate with this module, including STM32, ESP32, Arduino, Raspberry Pi Pico,  and many others. The EVE2 graphics controller handles all display rendering and touch processing, so the host MCU only needs to send graphics commands via SPI, making it compatible even with low-pin-count and low-performance microcontrollers.

Q: Can I use both the IDC header and the FFC connector simultaneously? A: No, CN1 (IDC Box Header) and CN2 (FFC Connector) share the same pin assignments and are designed as alternative connection options. You should use only one connection method at a time. Choose the option that best matches your PCB layout and mechanical design.

Q: What is the advantage of the onboard EVE2 controller compared to a standard TFT module? A: The EVE2 controller eliminates the need for a separate graphics processor, frame buffer RAM, and touch controller. It handles display initialization, graphics rendering, touch sensing, and audio playback all in one chip. This reduces BOM cost, PCB complexity, power consumption, and firmware development time. Applications that would typically require an high-end microcontroller with TFT-LCD controller can use a simpler, lower-cost SPI-enabled MCU instead.

Q: Does the anti-glare surface affect touch sensitivity? A: No, the anti-glare (AG) surface treatment is applied to the outer surface of the glass lens cover and does not affect the capacitive touch sensitivity or accuracy. The AG treatment reduces reflections from ambient light sources, improving readability without compromising touch performance.

Q: What is the lifespan of the LED backlight at 900 cd/m² brightness? A: The LED backlight is rated for typically 30,000 to 50,000 hours of operation at rated current. The onboard LED driver with PWM control allows the backlight brightness to be adjusted, which can extend the backlight lifespan when operating at reduced brightness levels in indoor environments.
