Product Introduction

1. Overview​
The CH154QV09A-LS redefines compact display aesthetics and performance as a 240*240 1.54 inch small ips tft display with round cover—a unique solution tailored for devices that demand both functional excellence and visual appeal. Developed to address the gap between miniaturization and design versatility, this module combines a 1.54-inch IPS TFT screen with a sleek round cover, creating a distinctive look that stands out in smart wearables, mini sensors, and small home appliances. With a module size of φ49.8×3.52(T) mm and a lightweight build (optimized for portability), it fits seamlessly into devices where space is at a premium, while its square active area (27.72(W)×27.72(H) mm) ensures balanced content display for icons, text, and simple graphics. Compliant with RoHS standards and backed by reliable performance metrics, it caters to eco-conscious manufacturers and end-users seeking durability in compact electronics.​
2. Design & Aesthetics: Round Cover for Unique Visual Identity​
A key differentiator of the CH154QV09A-LS is its round cover, which departs from the conventional rectangular designs of most small displays. This circular form factor adds a touch of elegance and nostalgia, making it an ideal choice for vintage-style smart watches, retro-themed mini gadgets, or home appliances where design harmony is prioritized. The round cover not only enhances visual appeal but also provides structural protection for the underlying IPS TFT screen, shielding it from minor scratches and impacts in daily use. Despite the round outer design, the 27.72×27.72 mm square active area maximizes usable display space, ensuring that 240×3(RGB)×240 pixels resolution is fully utilized to deliver sharp, detailed content—striking a perfect balance between style and functionality.​
3. Display Performance: IPS Clarity & Color Accuracy​
At the core of the CH154QV09A-LS is its high-performance IPS display system, engineered to deliver consistent visual quality from all angles. The 80/80/80/80 all-around viewing angles eliminate the color distortion and brightness loss common in non-IPS displays, allowing users to check content—whether fitness data on a smart watch or sensor readings on a portable device—from the front, sides, or slightly tilted positions without compromise. Complementing the wide viewing angles is an 800:1 contrast ratio, which enhances the depth of dark tones and the vibrancy of bright colors, making text crisper and graphics more vivid.​
The 240×3(RGB)×240 pixels resolution, paired with an RGB vertical stripe color filter array, supports rich 262K color reproduction, ensuring that even subtle color gradients (e.g., in interface themes or data visualizations) are rendered accurately. The 200 cd/m² luminance, powered by a long-lasting white LED backlight (20,000-hour lifespan), provides sufficient brightness for indoor use—from home environments to office settings—without consuming excessive power, making it suitable for battery-powered devices like portable sensors or smart wearables.​
4. Integration Ease: SPI Interface & Compact Dimensions​
The CH154QV09A-LS is designed with product developers in mind, featuring an SPI (Serial Peripheral Interface) that simplifies connection to host controllers. With 12 pins and a 0.35 mm pin pitch, the interface minimizes wiring complexity, saving valuable space on circuit boards and reducing integration time—critical for compact devices where every millimeter counts. The module’s slim 3.52 mm thickness and circular shape further enhance its adaptability: it can be embedded into curved surfaces (e.g., the bezel of a vintage smart watch) or flat panels (e.g., a mini home appliance control panel) without requiring major design modifications.​
Unlike displays with complex mounting requirements, the CH154QV09A-LS’s standardized dimensions and interface ensure compatibility with common embedded systems, allowing engineers to quickly prototype and scale products—from small-batch gadgets to mass-produced consumer electronics. This ease of integration, combined with the display’s unique round design, gives developers the flexibility to prioritize both functionality and aesthetics in their products.​
5. Durability & Environmental Adaptability​
Built to withstand daily use and diverse environmental conditions, the CH154QV09A-LS offers impressive durability and temperature tolerance. Its operating temperature range of -20~+70°C and storage temperature range of -30~+80°C ensure stable performance in extreme scenarios—from cold winter outdoor use (e.g., a smart watch worn during hiking) to warm indoor environments (e.g., a kitchen appliance control panel). This wide temperature range prevents common issues like screen flicker, backlight dimming, or response delays, ensuring reliable operation year-round.​
The white LED backlight’s 20,000-hour lifespan translates to over 2 years of continuous use, reducing the need for maintenance or replacement—particularly valuable for devices that are difficult to disassemble (e.g., sealed portable sensors). Additionally, RoHS compliance guarantees that the module contains no hazardous substances (e.g., lead, cadmium), aligning with global environmental regulations and making it a responsible choice for manufacturers committed to sustainable production.

Product Features

  • 1.54-Inch Size with Round Cover & Square Active Area：Features a 1.54-inch display integrated with a round cover (module size: φ49.8×3.52(T)mm) and a 27.72(W)×27.72(H)mm square active area. The round cover adds a retro-elegant aesthetic (ideal for vintage smart watches) while protecting the screen, and the square active area maximizes usable space for balanced content display—blending style and functionality.

  • 240×3(RGB)×240 High-Definition Resolution：Boasts 240×3(RGB)×240 pixels resolution and an RGB vertical stripe color filter array. It renders small text (e.g., fitness metrics, sensor data) and simple graphics with sharp detail, supporting 262K vivid colors—ensuring clear visualization of multi-segment content on the compact screen.
  • 80/80/80/80 All-Around IPS Viewing Angles：Adopts IPS/Transmission/Normally Black display mode, achieving 80/80/80/80 all-viewing angles. Users can check content from front, sides, or tilted positions without color distortion or brightness loss—critical for smart wearables where viewing angles vary frequently.
