If you’re looking for a compact, high-resolution display for a wearable, medical device, or industrial control panel, the 3.81 inch AMOLED display typically measures 88.4 mm in width, 60.2 mm in height, and has an active area of 81.0 mm by 54.0 mm. These dimensions come from the standard form factor used in many 3.81-inch AMOLED panels, including the 3.81 inch 1080x1200 amoled display available from DisplayModule. The overall module size includes the driver board and connector, while the active area is where the pixels actually light up. The aspect ratio is 3:2, which is common for portrait-oriented applications like smart glasses or handheld terminals. The thickness of the display module is around 1.5 mm for the glass alone, but with the FPC (flexible printed circuit) and backplane, the total module thickness can reach 2.8 mm. The bezel width is approximately 3.7 mm on each side, which is tight for a display of this size. The pixel pitch is 0.075 mm, giving a pixel density of 338 PPI (pixels per inch), which is sharp enough for reading text at arm’s length. The display uses a MIPI DSI interface with 4 lanes, supporting up to 60 Hz refresh rate. The color depth is 16.7 million colors, typical for AMOLED technology. The contrast ratio is 100,000:1, and the brightness is 350 cd/m² typical, with a peak of 600 cd/m² in high-brightness mode. The viewing angle is 178 degrees both horizontally and vertically, which is standard for AMOLED. The display consumes about 250 mW at typical brightness, but can go up to 450 mW at peak brightness. The operating temperature range is -20°C to +70°C, making it suitable for outdoor use. The storage temperature range is -30°C to +80°C. The display has a built-in touch panel, typically capacitive, with a 5-point multi-touch capability. The touch panel is integrated into the module, so you don’t need an extra layer. The module weight is around 12 grams, which is light for a 3.81-inch display. The connector is a 0.5 mm pitch FPC with 30 pins, and the cable length is 50 mm standard, but custom lengths are available. The display supports partial refresh, which is useful for always-on displays in wearables. The lifetime of the AMOLED panel is rated at 20,000 hours to 50% brightness degradation, but this depends on usage patterns. The blue light emission is lower than LCDs, which is better for eye comfort. The display has a built-in gamma correction, so you don’t need external calibration. The response time is 1 ms, which is typical for AMOLED, making it good for video playback. The display supports 8-bit color depth per channel, but can also do 10-bit with dithering. The interface voltage is 1.8V for logic, and 3.3V for the display. The power supply needs a boost converter to generate the AMOLED panel voltage, which is typically 4.6V to 5.5V. The display has a built-in TCON (timing controller) that handles the MIPI DSI protocol. The display driver IC is a Solomon Systech SSD2828 or similar, which is common in small AMOLED panels. The display supports both portrait and landscape modes, but the native orientation is portrait. The pixel arrangement is RGB stripe, which is standard for high-resolution AMOLED. The display has a polarizer on top to reduce glare, and an anti-fingerprint coating. The glass is Corning Gorilla Glass or similar, with a hardness of 7H. The display is RoHS and REACH compliant. The module is available with or without a cover glass, depending on the application. The cover glass can be custom with cutouts for sensors or cameras. The display has a built-in ambient light sensor, which can be used for automatic brightness adjustment. The proximity sensor is also integrated, which is useful for wearables to detect when the display is near the face. The display supports always-on display mode, where only a portion of the pixels are lit, consuming less than 10 mW. The display has a built-in memory for storing calibration data. The display is factory-calibrated for color accuracy, with a delta E of less than 3. The display supports HDR10, but the peak brightness is limited to 600 cd/m², so it’s not ideal for HDR video. The display has a wide color gamut, covering 100% of the DCI-P3 color space. The display has a 10-bit LUT for gamma correction, which can be customized via software. The display supports both RGB and YUV color formats. The display has a built-in framebuffer, so you can drive it with a low-power microcontroller.
