1. Document Overview

️· Type: LCD Module Specification Sheet
️· Manufacturer: Jewel Electronic Co., Ltd.
️· Document ID: JH40480800A
️· Version: 1.0
️· Date: August 13, 2013

2. Key Features and General Information

️· RoHS Compliant: The module meets RoHS environmental standards.
️· Warranty: The document mentions a warranty (details not specified).
️· Revision History: Includes a table of changes made to the document (currently only the initial version).

3. Electrical Characteristics (Not Explicitly Listed)

️· While specific electrical characteristics (voltage levels, power consumption, interface details) are not included in this document, they would be covered in a more detailed datasheet. This sheet focuses on mechanical, environmental, and handling aspects.

4. Mechanical and Physical Characteristics (Not Fully Specified)

️· No dimensions or precise mechanical details are provided in this extract. A complete specification would include these.

5. Reliability and Test Conditions

️· The document refers to reliability testing and conditions, but specifics are omitted.

6. Handling Precautions (Very Detailed)

This is the most extensive section, outlining critical guidelines for handling and storing the LCD module to prevent damage. Key points:

️· Fragility: The display panel is made of glass and polarizer, making it susceptible to damage from impact or stress.
️· Cleanliness: Avoid touching the display surface with bare hands, as oils can degrade insulation and the polarizer.
️· Solvents: Use only isopropyl or ethyl alcohol to clean; avoid water, ketones, or aromatic solvents.
️· Storage: Store in a sealed bag, away from sunlight and within a specified temperature range.
️· Electrostatic Discharge (ESD): Avoid touching sensitive areas to prevent ESD damage.
️· Avoid Permanent Images: Avoid displaying the same pattern for extended periods.

7. Cosmetic Defect Criteria

️· Glass Defects: Defines acceptance criteria for chip size on corners and edges of the glass, including limits on size and placement.
️· Polarizer Defects: Specifies acceptable limits for dent/bubble size and location.
️· Creaks: Not allowed.
️· Defect Zones (X, Y, Z): Defines zones where defects are acceptable.

8. Storage Conditions

️· Temperature: 0°C to 35°C
️· Protection: Sealed polyethylene bag
