Yousee Display module TFT LCD YX16901A
The document details the specifications for the YX16901A display module by Shenzhen Yousee Technology Co., Ltd. It features a 1.69-inch a-si TFT LCD with a resolution of 240(RGB) x 280 dots, a white LED backlight, and uses the ST7789V driver IC with a 4SPI interface. The module operates at an input voltage of 2.8±0.1 V.
Includes dimensions and assembly instructions, highlighting the use of integrated adhesive frames and steel sheet reinforcement.
The interface has 14 pins for power supply, ground, serial data input, and control signals for backlight and reset functions.
Operational supply voltage ranges from -0.3 to +4.6 V, withstanding temperatures from -20 to +70°C during operation and -30 to +80°C during storage.
Analog operating voltage is 2.4 to 3.3 V, and logic operating voltage is 1.65 to 3.3 V. Input and output voltage levels are specified for high and low states.
Features 3 LEDs in parallel with a forward voltage of 3.0 to 3.3 V at 60mA.
Offers a contrast ratio of 800 and a luminance of 300 Cd/m², with viewing angles of 80 degrees in all directions.
Details power on/off sequences for 2-power and 3-power configurations, with a reference to the IC specification for details.
Provides reset signal timing details, with a reference to the IC specification for further information.
Includes a workflow chart outlining the production process, responsibilities, and related documentation for quality control.
Details inspection criteria for defects such as point defects, line defects, and glass damage, with specific allowable limits.
Includes high and low temperature storage and operation tests, with specific conditions and post-test inspection criteria to ensure no defects like air bubbles, seal leaks, or glass cracks.
1. Temperature cycle alternates between -20℃±2℃, 25℃, and 70℃±2℃ for 10 cycles.
2. Damp proof test at 55℃±5℃ with 90% relative humidity for 48 hours.
1. Samples undergo appearance and functionality tests before ESD testing.
2. Air discharge applied at ±8KV, with a minimum interval of 5 seconds between discharges.
3. Testing stops for problem assessment if a sample fails.
Handling Precautions
1. Handle the display panel carefully to avoid mechanical shock.
2. Avoid excessive force on the display surface.
3. Handle the polarizer with care to avoid scratches.
4. Ensure tools are properly grounded to prevent electromagnetic interference.
1. Handle modules with care to prevent damage.
2. Use anti-static gloves and handle by edges.
3. Avoid stacking modules or using sharp objects.
4. Follow correct power on/off sequences.
5. Avoid long-term display of the same pattern to prevent ghost images.
6. Maintain specified temperature and humidity ranges.
1. Store in sealed polyethylene bags in a dark place, maintaining temperature between 0~35℃ and humidity between 40%RH and 60%RH.
2. Avoid contact between the polarizer surface and other objects.
1. Handle with care during shipment.
2. Ensure waterproof and moisture-proof measures.
1. Specifications are binding for quality inspection.
