Product catalog summary

General Information
The document provides specifications for the YX70022D TFT-LCD display module by Shenzhen Yousee Technology Co., Ltd. It is a 7.0-inch module with a resolution of 1200(RGB) x 1920 dots, featuring a white LED backlight and a MIPI interface.

Module Outline Drawing
Detailed schematics are included, highlighting the importance of maintaining specific tolerances to prevent light leakage and ensure proper fit within device housings.

Interface Description
The module uses a MIPI interface, standard for high-speed data transmission in display modules.

Absolute Maximum Ratings
Maximum voltage and temperature limits are specified: logic supply voltage (IOVCC) should not exceed 3.6V, and the operating temperature range is -20°C to 70°C.

Electrical Characteristics
Typical operating voltages are 3.3V for analog and 1.8V for logic circuits. Specific values for VGH, VGL, AVDD, and VCOM are not provided, indicating they may depend on application requirements.

Backlight Characteristics
The backlight consists of 56 LEDs in a series-parallel configuration, with a typical forward voltage of 22.4V at 160mA.

Optical Characteristics
The display offers a contrast ratio of 800:1, brightness of 2000 cd/m², an 80-degree viewing angle in all directions, and a response time of 25 ms.

Recommended Operating Sequence
Power on/off sequences are provided for 2-power and 3-power configurations, with a note to refer to the IC specification for details.

Production Process Control
A detailed workflow for production is outlined, including quality checks and corrective actions for nonconforming products.

Inspection Specifications
Criteria for visual and functional inspection are detailed, including allowable defect sizes and quantities for various imperfections.

Reliability Test Conditions
Tests include high and low temperature storage, temperature cycling, and humidity resistance, with criteria for post-test inspection to ensure no defects like air bubbles or glass cracks.

Precautions for Using LCD Modules
Handling precautions emphasize the fragility of the glass and polarizer, advising against excessive force and contact with hard objects. Proper grounding of assembly tools is recommended to prevent damage.

Handling Precautions for LCM

Ensure tools are grounded to minimize electromagnetic interference.
Handle LCM with care, using anti-static gloves and holding by the edges.
Avoid stacking LCMs or using sharp objects 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, resolved by resting the display.
Maintain temperature and humidity within specified ranges to prevent degradation.

Storage Precautions

Store LCMs 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.

Transportation Precautions

Handle with care to avoid damage to packaging; do not stack cartons over two meters high.
Ensure waterproof and moisture-proof measures during transportation.

Packing Specification

Dimensions: 370*300*150

Special Remarks

Specifications are binding for quality inspection.
Customers should report any issues or disagreements promptly.
Yousee is not responsible for damages due to neglect of precautions.
Limited warranty covers functional defects for one year from shipment date, unless otherwise agreed.
