What are the dimensions of a 5 inch 1080x1080 round TFT?

If you’re looking for a 5 inch round TFT with a 1080x1080 resolution, the active area dimensions are 88.5 mm by 88.5 mm, forming a perfect square within the circular display. The overall module size, including the bezel and FPC (flexible printed circuit), typically measures around 97.5 mm in width and 97.5 mm in length, with a thickness of approximately 1.5 mm to 2.0 mm depending on the touch panel integration. The circular shape means the visible display area is a circle with a diameter of 88.5 mm, which is exactly the diagonal of the active area square. So, when you hear “5 inch,” it refers to the diagonal of the square active area, not the circle’s diameter—though in this case, they’re identical because the resolution is square. This specific panel, the 5 inch 1080x1080 round tft display, uses a MIPI interface with the HX8399 driver IC, and its pixel density is a crisp 308 PPI (pixels per inch), calculated from the 1080 pixels across 88.5 mm. The circular cutout is achieved through a custom mask during manufacturing, so the physical glass is round with a diameter of about 95.0 mm including the bezel, leaving a 3.25 mm border on each side for the frame and sealing. The FPC length is usually 30.0 mm to 40.0 mm, with a width of 10.0 mm to 15.0 mm, and it includes a ZIF connector with 40 pins at a 0.5 mm pitch. The viewing angle is 80 degrees in all directions (top, bottom, left, right), typical for IPS technology, and the brightness is rated at 400 cd/m² to 500 cd/m², which is sufficient for indoor use but may require an optical bonding for outdoor applications. The contrast ratio is 1000:1, and the response time is 25 ms, making it suitable for static images and moderate video playback. The operating temperature range is -20°C to +70°C, and the storage temperature is -30°C to +80°C, which is standard for consumer electronics. The weight is around 50 grams to 70 grams, depending on whether a capacitive touch panel is included. The touch panel, if integrated, adds 0.5 mm to 1.0 mm thickness and increases the overall weight by 10 grams to 20 grams. The interface uses a 4-lane MIPI DSI, supporting a 24-bit RGB color depth, and the refresh rate is 60 Hz. The power consumption is typically 1.5 W to 2.5 W at full brightness, with the backlight consuming the majority of that. The backlight is an LED array with 6 to 8 LEDs, and the lifetime is rated at 30,000 hours to 50,000 hours. The module is designed for applications like smart home devices, automotive dashboards, and industrial control panels, where a circular form factor is needed for aesthetic or functional reasons. The round shape requires careful PCB layout to avoid interference with the display driver, and the FPC must be routed to avoid stress on the glass. The module uses a COG (chip-on-glass) bonding process, which reduces the overall thickness and improves reliability. The glass substrate is 0.5 mm thick, and the polarizer is 0.1 mm thick, so the total glass stack is about 0.8 mm. The bezel is made of stainless steel or plastic, depending on the manufacturer, and it includes mounting holes for M2 screws at a 4.0 mm distance from the edge. The connector is a 0.5 mm pitch ZIF, and the pinout is standard for MIPI displays, with power rails at 3.3 V for logic and 2.8 V for analog. The backlight voltage is 3.0 V to 3.3 V, with a current of 200 mA to 300 mA. The module is RoHS compliant and has a CE marking for European markets. The color gamut is 70% NTSC, which is typical for TFT-LCD panels, and the color depth is 16.7 million colors. The gamma correction is 2.2, and the white point is at 6500K. The module supports a sleep mode with power consumption below 0.1 W. The interface speed is 500 MHz per lane, and the total data rate is 2 Gbps, which is sufficient for 1080x1080 at 60 Hz with 24-bit color. The horizontal blanking is 20 pixels, and the vertical blanking is 10 lines, so the total pixel clock is about 70 MHz. The module is compatible with most ARM-based SoCs, like the Raspberry Pi, BeagleBone, and STM32, but requires a custom driver for the HX8399 IC. The initialization sequence is provided by the manufacturer, and it includes commands for sleep out, display on, and gamma correction. The module has a built-in TCON (timing controller) that handles the MIPI to parallel conversion. The power sequence requires a specific order: first VDD, then VCI, then backlight, and finally the MIPI data. The module is sensitive to ESD, so proper grounding is required during handling. The viewing angle is 80 degrees in all directions, but the contrast ratio drops to 500:1 at 60 degrees. The module is available in both portrait and landscape orientations, but the circular shape makes it orientation-independent. The touch panel, if used, is a projected capacitive type with a 5-point multi-touch capability, and it uses an I2C interface with a touch controller like the FT6336. The touch panel has a cover glass thickness of 0.5 mm to 1.0 mm, and it is optically bonded to the TFT to reduce glare. The touch panel’s response time is 10 ms, and it supports gestures like tap, double-tap, and swipe. The module is tested for 1000 hours at 60°C and 90% humidity, and it has a MTBF of 50,000 hours. The packaging is a vacuum-sealed bag with a desiccant, and the module is shipped in a tray with ESD protection. The price is around $30 to $50 per unit, depending on the quantity and whether the touch panel is included. The module is available from distributors like DisplayModule, and it has a lead time of 2 to 4 weeks for small quantities. The module is also available with a custom bezel or mounting bracket for specific applications. The circular shape requires a customized display driver to handle the non-rectangular pixels, but the HX8399 supports a circular window mode that masks the corners. The module’s pixel layout is RGB stripe, and the sub-pixel size is 0.027 mm by 0.081 mm, which is typical for high-resolution displays. The aperture ratio is 60%, and the transmittance is 5% to 10% for the LCD layer. The backlight is edge-lit, with LEDs on one side, and the light guide plate is 0.5 mm thick. The uniformity of the backlight is 80% to 90%, and the color temperature is 6500K with a tolerance of 500K. The module is designed for a wide range of applications, including smartwatches, smart home hubs, and automotive instrument clusters. The circular form factor is also popular in medical devices, where a round display is used for circular gauges or dials. The module’s dimensions are critical for mechanical integration, and the 88.5 mm active area diameter means the cutout in the enclosure must be at least 90.0 mm to accommodate the bezel. The module’s thickness of 1.5 mm to 2.0 mm is thin enough for most handheld devices, but it may require a reinforcement bracket for larger enclosures. The FPC is flexible and can be bent to a radius of 2.0 mm, but repeated bending may cause damage. The module is rated for 100,000 bending cycles at a 5.0 mm radius. The connector is a 0.5 mm pitch ZIF, and it is rated for 10,000 insertion cycles. The module is also available with a custom connector or cable for specific applications. The module’s resolution of 1080x1080 means it has 1,166,400 pixels, and each pixel is 0.082 mm by 0.082 mm. The pixel density of 308 PPI is higher than most smartphone displays, which are typically 300 PPI to 400 PPI. The module’s color depth is 24-bit, which means it can display 16.7 million colors, and the color accuracy is 70% NTSC. The module’s brightness is 400 cd/m² to 500 cd/m², which is sufficient for indoor use, but for outdoor use, a brightness of 1000 cd/m² or more is recommended. The module’s contrast ratio is 1000:1, which is typical for IPS displays, and the viewing angle is 80 degrees in all directions. The module’s response time is 25 ms, which is fast enough for most applications, but for gaming or video, a response time of 10 ms or less is preferred. The module’s power consumption is 1.5 W to 2.5 W, which is low for a display of this size, but it can be reduced by using a lower brightness or a sleep mode. The module’s interface is MIPI DSI, which is standard for mobile displays, and it requires a 4-lane configuration with a clock speed of 500 MHz. The module is compatible with most microcontrollers and SoCs that support MIPI DSI, such as the Raspberry Pi, STM32, and i.MX series. The module’s driver IC is the HX8399, which is a common IC for high-resolution displays, and it supports a variety of display modes, including video mode and command mode. The module’s initialization sequence is provided by the manufacturer, and it includes commands for setting the display resolution, color depth, and gamma correction. The module’s power supply requires a 3.3 V logic voltage and a 2.8 V analog voltage, and the backlight requires a 3.0 V to 3.3 V voltage with a current of 200 mA to 300 mA. The module’s operating temperature range is -20°C to +70°C, which is standard for consumer electronics, but for industrial applications, a wider temperature range of -40°C to +85°C is available. The module’s storage temperature range is -30°C to +80°C, and it should be stored in a dry environment with a humidity of less than 60%. The module is sensitive to electrostatic discharge, so it should be handled with ESD protection, and it should be stored in an anti-static bag.
