Lists the limits for supply voltage, input voltage, operating temperature, storage temperature, and humidity.
Provides operating voltages for analog and logic circuits, with typical values.
Details the forward voltage and LED configuration for the backlight system.
Includes specifications for response time, contrast ratio, color gamut, luminance uniformity, viewing angle, and brightness, with notes on measurement methods.
Outlines the power on/off sequences for the module, referencing the IC specification for details.
Provides timing information for the reset signal, with a note to refer to the IC specification.
Describes the workflow and responsibilities for production, including quality control and handling of nonconforming products.
Lists criteria for defects and inspection standards, including point and line defects, and handling of nonconforming products.
Details various environmental and stress tests to ensure module reliability, including temperature, humidity, and ESD tests.
Provides handling and usage precautions to prevent damage to the LCD module, emphasizing care with the glass and polarizer.
- The LCD module's polarizer is soft and prone to scratches. Avoid contact with hard objects like glass or tweezers.
- Tools such as soldering irons must be grounded to prevent electrical leakage. Electric screwdrivers should also be grounded to minimize electromagnetic interference.
- Handle LCD modules with care, using anti-static gloves and holding by the edges.
- Avoid stacking modules or using sharp objects like pens on them.
- Apply logic voltage before analog voltage when powering on, and reverse the order when powering off.
- Long-term display of the same pattern may cause ghost images, which can be resolved by resting the module.
- Maintain temperature and humidity within specified ranges to prevent polarization degradation or bubble formation.
- Store LCD modules in sealed polyethylene bags in a dark place, maintaining temperature between 0-35°C and humidity between 40-60% RH.
- Avoid contact of the polarizer surface with other objects.
- Handle with care during shipment, ensuring packaging is intact and not stacked over two meters high.
- Ensure waterproof and moisture-proof measures are in place during transportation.
- Dimensions: 370*300*150 mm
- The specifications are binding for quality inspection.
- Customers should report any issues or disagreements with the specifications to Yousee Technology.
- Yousee is not responsible for damages due to neglect of precautions.
- Yousee offers a one-year warranty for functionally defective products, unless otherwise agreed.
