3. Exhaustive Technical Specifications

3.1 General Specification Summary

3.2 Electrical & Optical Characteristics

The specification provides a table for "Electrical-Optical Characteristics (Ta=25°C)" with the following key parameters extracted from the document's general specification section:

Note: Data extracted from the "General Specification" section of the PDF. The dimensions table in the document also indicates typical mechanical tolerances (±0.2mm for most dimensions) and specific values for the active area (135.36 mm × 216.55 mm approx) and module outline (143 mm × 228.6 mm approx), with a thickness specification of 2.82 mm (Typ). Panel brand is noted as BOE 10.1 inch.

3.3 Quality Inspection Standards (Inspection Range & Defect Criteria)

The specification defines standard quality inspection terms for dot and line defects:

• Dot Defect Area Division: For dot defects on TFT LCDs not smaller than 3 inches, the active area is divided into three zones for judgment:
  • A Area (AAA area): Center of viewing area.
  • B Area: Periphery of viewing area (1/5 of the active area from each edge).
  • C Area: Outside viewing area.
• Other Defect Area Division: For other defects (e.g., scratches, particles), the viewing area is divided into two zones:
  • A Zone: Inside Viewing Area.
  • B Zone: Outside Viewing Area.
• Glass Defect Crack Criteria (Example):
  • Front of lead terminals (A): a ≤ t (glass thickness), b ≤ 1/5 W (lead width), c ≤ 3mm. Max. 3 defects allowed.
  • Crack at two sides of lead terminals (B): Should not cover patterns and alignment marks. Max. 3 defects allowed.

Note: The figures in the document show the distances from Active Area (A.A) to Viewing Area (V.A) as X1 = X2 = Y1 = Y2 = 2mm.

3.4 LED Circuit & Timing

The specification includes a section for "LED CIRCUIT" and timing parameters for the TFT LCD panel's driving signals. Key timing values from the gate and data signal table include:

4. Application Guidelines & Critical Notes

Intended Use

• Primary Application: Tablets and Mini-PCs.
• General embedded display applications requiring a 10.1-inch WXGA (800×1280) resolution screen.
• Suitable for portable devices where thin glass (0.5t/0.4t) and moderate transmittance (6.5%) are acceptable.

Critical Design Considerations

1. Resolution (800×1280 WXGA): This is a standard portrait-oriented WXGA resolution (8:12.8 aspect ratio, similar to 5:8). The host graphics system must support this specific timing.
2. Glass Thickness: The use of 0.5t Array Glass and 0.4t CF Glass results in a thinner and lighter module compared to standard thicknesses (0.7t typically). This requires careful mechanical design to avoid excessive stress on the thinner glass during mounting.
3. High Transmittance (6.5%): The spec highlights a "High Transmittance" of 6.5%. This allows for a lower-power backlight or a brighter display for the same backlight power. This is a key benefit for battery-operated devices.
4. Operating Temperature Range: The operating temperature range is -20°C to +50°C. Note that this is an upper limit of +50°C, which may be restrictive for some industrial or automotive applications. The storage temperature, however, is a wider -20°C to +60°C.
5. BOE Panel: The outline drawing references "BOE 10.1 inch", confirming the panel is sourced from BOE, a major LCD manufacturer.
6. Backlight Driving: The backlight requires a constant current source of 160mA typical, with a forward voltage of 12V (Typ.) (range 11.2V to 12.8V).
7. Defect Inspection: The specification's definition of A/B/C zones for dot and line defects indicates the standard quality criteria. The acceptable number and size of defects are governed by these inspection standards.

Handling & Compliance

• The module is ROHS Compliant as indicated in the document.
• Observe standard ESD precautions during handling and assembly.
• The module contains fragile glass (especially the thinner 0.4t/0.5t glass) and a precision FPC – handle with care.
• Do not attempt to disassemble or modify the LCD module.
• All NC (No Connect) terminals should be left open.

5. Conclusion & Design-In Support

The LS101I19-MP-V1 specification details a standard 10.1-inch WXGA (800×1280) TFT display module featuring thinner glass (0.5/0.4t) and higher transmittance (6.5%) than typical TN panels, optimized for portable tablet and mini-PC applications.

Key Strengths

• Enhanced Transmittance: 6.5% transmittance contributes to better power efficiency or higher brightness.
• Thinner Glass Profile: 0.5t and 0.4t glass reduces module weight and thickness.
• Standard 10.1-inch Size: Fits the common form factor for tablets and portable PCs.
• WXGA Resolution (800×1280): Provides detailed images suitable for reading and media consumption.
• BOE Panel Backing: Proven panel quality from a reputable manufacturer.

Main Design Focus

• The critical design task is integrating the module into a thin, portable device enclosure, taking advantage of the weight savings but handling the thinner glass with care.
• Supporting requirements: Provide a constant current backlight driver rated for 160mA at 12V. Ensure the host processor supports the 800×1280 (WXGA) resolution with the correct interface. Design a secure mounting system that does not stress the glass edges.

This module is an excellent choice for engineers developing cost-sensitive tablets or portable mini-PCs who need a proven, standard-definition 10.1-inch display optimized for thinness and efficiency.
