2.0-inch bar touch display: an efficient interactive solution in a small space
In scenarios such as smart wearable devices, smart home control panels, and portable instruments, traditional square displays are often difficult to fit into narrow spaces due to size limitations. The 2.0-inch bar touch display, with its unique 16:3 aspect ratio (length 60mm, width 11mm), enables clear information display and precise touch operation in a very small space, making it an ideal interactive interface for compact devices. Whether it is a side screen notification on a smartwatch, a status display on a coffee machine, or an operating guide for a portable blood glucose meter, this bar screen can enhance the user experience with its strong adaptability and quick response.
Display performance: small size and large amount of information
1. High-definition image quality and color performance
Resolution and pixel density: 240×48 pixel OLED display (pixel pitch 0.25mm), pixel density of 102PPI, clear text display without jagged edges, even small text such as "blood sugar value 5.2mmol/L" can be clearly read in the sun (brightness of 500cd/m², contrast ratio 10000:1).
Wide viewing angle and color reproduction: Supports 170° full viewing angle (horizontal/vertical), and the picture can be kept undistorted even if it deviates 80° from the front; 16-bit color depth (65536 colors) is used, and the color reproduction degree reaches 92% NTSC, and different colors can be used to intuitively distinguish the type of information (such as green for normal and red for warning).
2. Low power consumption and display mode
Dynamic refresh rate: supports 30Hz/60Hz adaptive refresh rate, automatically drops to 30Hz when static display, power consumption as low as 0.15W, and with the low power mode of the device, it can extend battery life (such as smart bracelets using this screen, the battery life can be extended by 15%).
Always on and off screen display: OLED self-luminous characteristics enable it to support partial always on (only display time or key data), power consumption is ≤0.01W when the screen is off, suitable for scenes that require real-time display of information (such as kitchen timers).
Touch function: Detailed design for precise operation
1. Sensitive touch and operation method
Capacitive touch technology: uses 2-point capacitive touch, supports sliding, clicking, long pressing and other operations, response time ≤50ms, and can be accurately identified even with thin gloves (touch accuracy ±0.5mm). On the smart thermometer, users can adjust the temperature unit (℃/℉) by sliding, and the operation is smooth and free of lag.
Anti-false touch algorithm: Built-in edge anti-false touch function, identify finger contact area (≥5mm²), avoid misoperation caused by small equipment (such as the side button false touch rate of the bar remote control is reduced to less than 0.5%).
2. Human-computer interaction optimization
Touch feedback: Support vibration feedback (built-in 0810 micro vibration motor), generate 50ms slight vibration when clicking, let the user know that the operation has taken effect, no visual confirmation is required.
Gesture quick operation: Support left and right sliding to switch interfaces, sliding up and down to adjust values, with dynamic guidance icons on the screen (such as arrow indicators), new users can also quickly get started (learning cost reduced by 40%).
Structural design: Advantages of adapting to small spaces
1. Lightweight and installation flexibility
Ultra-thin body: The display thickness is only 1.2mm (including the touch layer), and the overall weight is 0.8g. It can be embedded in small spaces such as watch straps and device sides (the minimum installation space requires 62mm×13mm×2mm), without affecting the overall appearance and grip of the device.
Multiple installation methods: Support COG (Chip On Glass) packaging, the length of FPC cable can be customized (10-50mm), adapted to the internal structure of different devices; provide two installation methods, patch type and clip type, to meet the needs of automated production (patch accuracy ±0.1mm).
2. Durability and environmental adaptability
Anti-scratch and protection: The surface is covered with 0.1mm thick tempered glass (Mohs hardness 7), which has passed 1000 steel wool friction tests (500g pressure) without scratches, suitable for scenes with frequent daily contact (such as the bar screen of the access card).
Wide temperature and stability: The operating temperature range is -20℃ to 70℃, and it can work normally in low temperature environment (such as refrigerator thermometer) or high temperature environment (such as oven control panel), with no screen flicker and no touch delay.
Applicable scenarios: Multiple applications for small space interaction
1. Smart wearable devices
Smart watch side screen: As a supplement to the main screen, it displays notification previews (such as "Call: Zhang San") or shortcut functions (such as heart rate, number of steps), and users can quickly obtain information without turning their wrists.
Sports bracelet: The bar screen adapts to the narrow and long shape of the bracelet, displays sports data (such as pace, distance), supports sliding to switch different sports modes, and is easy to operate.
2. Smart home and small appliances
Coffee machine/microwave oven: Displays status information such as remaining heating time and temperature. Users can adjust parameters by touch (such as increasing the heating time from 30 seconds to 1 minute).
Smart door lock: Embedded on the side of the door handle, it displays states such as "unlocked" and "low battery", supports touch input of temporary passwords, and adapts to the narrow and long structure of the door lock.
3. Medical and health equipment
Blood glucose meter/blood pressure meter: While displaying the test results, it guides users to complete the operation through touch (such as "Please insert the test strip" and "Measuring"), and the interface is simple and intuitive, suitable for the elderly.
Infusion alarm: The bar screen displays the remaining liquid volume and flow rate, supports touch adjustment of the alarm threshold, and is small enough to be fixed on the infusion tube.
Technical parameters and customization options
Core parameters: 2.0 inches (50.8mm diagonal), 16:3 ratio, 240×48 resolution, 500cd/m² brightness, 2-point capacitive touch, -20℃ to 70℃ operating temperature.
Customization options: Support screen length customization (40-80mm), increase in touch points (up to 5 points), and adjustment of the FPC cable interface position to meet the personalized needs of different devices.
