Product catalog summary

General Information
The document details the specifications for a TFT/Transflective LCD module with a recommended viewing direction at 3:00 O’ Clock. The module dimensions are 50.00×69.20×2.85 mm³, with an active area of 43.20×57.60 mm². It features 240RGB×320 dots and uses an HX8367-A driver IC. Interface types include MCU/SPI/RGB, operating at an input voltage of IOVCC=1.8V and VCC=2.8V, consuming 208 mW of power.

Absolute Maximum Ratings
The module can withstand input and supply voltages between -0.3V and 4.6V. It operates within a temperature range of -20°C to 70°C and can be stored between -30°C and 80°C. Humidity should not exceed 90% at 60°C.

Electrical Characteristics
The I/O power supply ranges from 1.65V to 3.3V, and the supply voltage for logic is between 2.5V and 3.3V. Input and output voltage levels are specified for both high and low states.

Backlight Characteristics
The backlight uses 4 LEDs in a parallel connection, with a forward voltage ranging from 2.9V to 3.4V at a constant current of 60mA.

Electro-Optical Characteristics
Response time is between 35ms and 55ms, with a contrast ratio of 36 to 72. The surface luminance is 90 to 120 cd/m², and the viewing angle varies depending on the direction, with a maximum of 45 degrees.

Interface Description
The interface includes multiple pins for system interface selection, reset, synchronizing signals, data bus, and power supply connections. Specific pins are designated for serial data input/output and LED driving.

Reliability Test Conditions
The module undergoes various tests, including high and low temperature storage and operation, temperature cycling, damp proof testing, vibration, dropping, and ESD tests. Each test has specific conditions and criteria for inspection post-testing.

Inspection Criterion
The inspection criteria are based on functional and cosmetic defects, with specific standards for major and minor defects. The document outlines acceptable quantities for defects in different zones of the LCD.

Inspection Criteria for 4.3" MDS Product

Glass Defects: Chips on corners should not extend into the ITO pad or expose the perimeter seal. Usual surface cracks should not extend beyond the inner border line of the seal. Cracks that tend to break are considered major defects.
Parts Alignment: IC and FPC/heat-seal lead width should not exceed 50% beyond the lead pattern. Chips or solder components should not be off-center by more than 50% of the pad outline.
SMT Standards: Follow IPC-A-610E class 2 standards. Missing components or functional defects are major defects, others are minor.

Handling Precautions for LCD Modules

General Handling: Avoid dropping or applying mechanical shock. Do not apply excessive force to the display surface. Handle the polarizer carefully to avoid scratches.
Cleaning: Use isopropyl or ethyl alcohol for cleaning. Avoid water, ketone, or aromatic solvents.
Electrostatic Discharge: Ensure proper grounding when handling LCD modules to prevent static damage.

Storage and Transportation

Storage: Store in a sealed polyethylene bag in a dark place at 0-35°C and 40-60% RH.
Transportation: Handle with care to avoid breaking the packaging. Ensure waterproof and moisture-proof measures are in place.

Installation and Soldering

Installation: Use mounting holes to avoid twisting or warping. Ensure proper spacing to avoid stress on the module.
Soldering: Follow specified temperature and time conditions for soldering. Protect the LCD surface during soldering to prevent damage.

Operation Precautions

Voltage: Operate within specified voltage limits to avoid shortening LCD life.
Temperature: Maintain within specified temperature range to avoid performance issues.

Warranty and Returns

Warranty: Yousee offers a one-year warranty for functionally defective modules. Cosmetic defects must be reported within 90 days.
Return Conditions: Warranty is void if handling precautions are disregarded, such as broken glass or modified circuits.

Packing Specification
Please consult the technical department for detailed information regarding packing specifications.

Prior Consultation Matters

For Yousee standard products, the company reserves the right to change materials and processes to improve product properties without prior notice to customers.
For OEM products, any changes that may affect product properties will be discussed with the customer in advance.
If there are special requirements regarding reliability conditions, customers should inform the company before testing samples.
