3.1 Mechanical & Physical Specifications

3.2 Electrical & Interface Specifications

3.2.1 Absolute Maximum Ratings

3.2.2 Electrical Characteristics

Note: The LVDS interface uses differential signals. The receiver interprets a differential voltage (VID) greater than +100mV as a HIGH level and less than -100mV as a LOW level, relative to a common mode voltage of 1.2V. The specification includes detailed LVDS DC Electrical Characteristics for both VDD=2.5V and VDD=3.3V operation, showing a differential input voltage (VID) range of 0.1V to 0.6V and a common mode voltage (VCM) for VDD=3.3V up to (2.4 - (|VID|/2))V.

3.2.3 Backlight Unit Characteristics

The backlight circuit is edge-lighting type with white LEDs. The electrical table provides key parameters:

Note: The backlight circuit requires a high-voltage supply (HVDD = 31V Typ) to drive the series-parallel LED string. The LED forward current per string is 19mA (Typ), and the total LED current is 76mA (Typ, from absolute max ratings). The power supply for the backlight driver is rated 31V (Typ) at 76mA, with a maximum of 34V. A dedicated boost-type constant current LED driver is required.

3.3 Signal Timing Waveforms (LVDS Interface)

The specification includes signal timing waveforms for Data Enable, Hsync, Vsync, and the LVDS differential clock (CLK). Key timing parameters indicated in the waveform diagram include:

• tCLK: Clock cycle period (0.5 Vcc threshold).
• tHP: Horizontal period.
• tWH: Hsync pulse width.
• tHFP / tHBP: Horizontal front porch / horizontal back porch.
• tVP: Vertical period.
• tWV: Vsync pulse width.
• tVFP / tVBP: Vertical front porch / vertical back porch.
• High/Low Levels: High = 0.7*VCC, Low = 0.3*VCC for Data Enable, Hsync, Vsync.

Note: The exact numeric timing values (in pixel clocks or lines) are not provided in the snippet but are described in section 6.2. The host LVDS transmitter must be configured to generate these timing parameters for a 1280x800 panel.

3.4 Electro-Optical Characteristics

Note: The display features exceptional viewing angles of 89° from all four directions (Top, Bottom, Left, Right) with CR > 10, indicating an IPS-like panel. The typical luminance is 450 cd/m², with a minimum of 400 cd/m². The typical contrast ratio is 900:1.

4. Application Guidelines & Critical Notes

Intended Use

• Standard 10.1-inch industrial, commercial, and embedded display applications.
• Applications requiring a WXGA (1280×800) resolution display with a standard LVDS interface.
• Systems requiring a bright display (450 cd/m²) with wide viewing angles (89°/89°/89°/89) and a wide operating temperature range (-20°C to +65°C).

Critical Design Considerations

1. Power Supply (VDD = 3.3V): The module requires a stable 3.3V power supply (VDD) for the LCD logic with an operating range of 3.0V to 3.6V. The maximum logic current consumption is 260mA.
2. High Backlight Power Supply Voltage (HVDD = 31V): The backlight requires a high-voltage supply of 31V (Typ) at 76mA (Typ), with a maximum of 34V and 80mA. This requires a dedicated boost-type constant current LED driver circuit capable of generating up to 35V from a lower system voltage rail.
3. External Backlight Driver Required: The module provides direct access to the LED strings, requiring an external constant-current LED driver. The backlight characteristics table shows an LED Forward Voltage (VF) of 3.1V (Typ) and Forward Current (IF) of 19mA (Typ) per LED string, with a total current of 76mA.
4. LVDS Interface with 4 Data Lanes: The module uses 4 LVDS data lanes (RXIN0 to RXIN3) plus one clock lane. The host LVDS transmitter must be configured for 4-lane, 8-bit mode at WXGA (1280×800) resolution. The differential input threshold is ±100mV with a common mode voltage (Vcom) of 1.2V.
5. Wide Viewing Angle (89°/89°/89°/89): The display offers a very wide viewing angle, characteristic of an IPS (In-Plane Switching) panel, making it suitable for applications where the screen is viewed from various angles.
6. Excellent Contrast (900:1) and Brightness (450 cd/m²): The module provides high contrast and brightness for clear visibility in well-lit indoor environments.
7. Operating Temperature Range (-20°C to +65°C): The module supports a wide operating temperature range, suitable for industrial applications. The storage temperature range is even broader (-40°C to +80°C).
8. Power Consumption (Total 3.55W Max): The typical total power consumption is 3.55W, consisting of LCD logic power (max 0.85W) and backlight power (max 2.7W). This is an important consideration for system power budgeting.
9. Response Time (25ms Typ): The response time (Tr+Tf) is typical of a-Si TFT-LCD displays, adequate for general multimedia and industrial applications but not ideal for high-speed gaming.
10. LED Lifetime (50000 Hours): The LED backlight is rated for 50,000 hours of operation (to 50% brightness at IF=20mA, Ta=25°C). Using constant current driving below the absolute maximum ratings can help maximize lifetime.

Handling & Compliance

• Observe standard ESD precautions during handling and assembly.
• The module contains fragile glass and a precision FPC – handle with care to avoid damage.
• Avoid bending the FPC sharply, especially near the connection point to the LCD glass.
• Do not attempt to disassemble or process the LCD Module.
• All NC (No Connection) terminals should be left open to avoid interference.
• If the logic circuit power is off, do not apply the input signals to avoid latch-up.

5. Conclusion & Design-In Support

The LS1010I06-L-V1 specification details a high-brightness, 10.1-inch WXGA (1280×800) TFT LCD module with wide viewing angles (89°/89°/89°/89), a standard LVDS interface, and a robust operating temperature range — an excellent choice for a wide variety of industrial, medical, and commercial display applications.

Key Strengths

• Excellent Optical Performance: High luminance (450 cd/m² Typ), high contrast ratio (900:1 Typ), and wide viewing angles (89° from all directions).
• Standard LVDS Interface with 4 Lanes: Easy to integrate with most embedded processors and FPGAs.
• WXGA Resolution (1280×800): A standard 16:10 aspect ratio, ideal for productivity and media applications.
• Wide Operating Temperature (-20°C to +65°C): Suitable for industrial environments.
• Long LED Lifetime (50,000 Hours): Provides long operational life.

Main Design Focus

• The critical design tasks are designing a boost-type external constant-current LED backlight driver capable of supplying ~76mA at up to 34V (to meet the HVDD requirement) and configuring the host's LVDS transmitter for a 4-lane, 8-bit, WXGA (1280×800) resolution display at 60Hz.
• Supporting requirements: Provide a stable 3.3V supply for VDD. Ensure the system can handle up to 3.55W of total power consumption. Design a secure mechanical housing that accommodates the module's dimensions and protects it from mechanical stress.

This module is a strong choice for engineers designing systems requiring a bright, high-contrast, full-viewing-angle display in a standard 10.1-inch format with a standard LVDS interface and robust environmental specifications.
