Yousee Display module TFT LCD YX45011A
The document details the specifications for the TFT-LCD module YX45011A by Shenzhen Yousee Technology Co., Ltd. It features a 4.58-inch display with a resolution of 320(RGB) x 960 dots, using a MIPI interface and driven by the ST7701S IC. The module dimensions are 40.37(W) x 117.9(H) x 2.08(T) mm, with an active area of 36.77(W) x 110.3(H) mm.
The module includes 30 pins for functions such as LED anode/cathode, power supply, reset signal, and MIPI DSI differential data pairs. It supports touch functionality with dedicated pins for touch interrupt, IIC data, and clock signals.
The module operates within a supply voltage range of -0.3V to +3.6V and functions in temperatures from -20°C to +70°C, with storage temperatures between -30°C and +80°C.
It requires an analog operating voltage between 2.65V and 3.5V, and a logic operating voltage between 1.65V and 3.3V.
The backlight consists of 8 white LEDs in series, with a forward voltage of 25.6V at 20mA.
The display offers a response time of 25ms, a contrast ratio of 1000:1 to 1200:1, and a brightness of 350 cd/m², with an 80-degree viewing angle in all directions.
Power on/off sequences are provided for both 2-power and 3-power configurations, with reference to the IC specification for detailed procedures.
A detailed workflow for production is outlined, including responsibilities and related documentation for quality assurance and corrective actions.
Criteria for defects such as point defects, line defects, and glass damage are specified, with allowable limits for each type.
The module undergoes tests including high/low temperature storage, temperature cycling, and ESD testing to ensure durability and performance.
Handling precautions emphasize the fragility of the glass and polarizer, advising against excessive force and contact with hard objects. Proper grounding of tools and careful handling to avoid scratches and stains are recommended.
- Electromagnetic Interference: Use grounded tools to minimize electromagnetic waves.
- LCM Handling Precautions: Handle LCD modules with care, using anti-static gloves and avoiding stacking or sharp objects.
- Power Sequence: Apply logic voltage before analog voltage when powering on, and reverse when powering off.
- Image Retention: Avoid prolonged display of the same pattern to prevent ghost images.
- Temperature and Humidity: Maintain specified conditions to prevent polarization degradation.
- Store in sealed polyethylene bags in a dark place, maintaining temperature between 0-35°C and humidity between 40-60% RH.
- Avoid contact with other objects to prevent damage to the polarizer surface.
- Handle with care during shipment, ensuring packaging integrity and limiting carton stacking height to two meters.
- Implement waterproof and moisture-proof measures during transportation.
- Dimensions: 370*300*150
- Specifications are binding for quality inspection. Customers should report any issues promptly.
- Yousee is not liable for damages due to neglect of precautions.
- Limited warranty covers functional defects for one year from shipment, unless otherwise agreed.
