3. Exhaustive Technical Specifications

3.1 Mechanical & Physical Specifications

3.2 Electrical & Interface Specifications

3.2.1 Absolute Maximum Ratings

The absolute maximum ratings are for supply voltage and temperature only.

3.2.2 Operating Electrical Characteristics

3.2.3 Serial Interface Characteristics (4-line Serial)

Logic levels are specified as 30% and 70% of VDDI for Input signals. (Ta=25°C, VDDI=1.65~3.7V, VDD=2.5~3.7V)

The timing diagram illustrates the relationship between CSX, SCL, SDA, and D/CX signals. Key parameters include TS, TH, and other setup/hold times.

3.2.4 Power On / Off Sequence

The power on/off sequence is illustrated in the specification. Key notes:

• Timing is defined at the crosspoint of 90% of typical value for the supply voltage.
• Trpw (Power on rise time) and Tfpw (Power off fall time): +/- no limit.
• Power down sequence: In sleep-out mode, the minimum RESX low pulse width is 120ms. In sleep-in mode, the minimum is 0ms.
• CSX and RESX timing has no limit on rise/fall time.

3.3 Electro-Optical Characteristics

The specification details the measurement setup and response time testing method.

• Measurement Setup: Measurements are made at the center of the C/F (Color Filter). A C-light source (Halogen Lamp) is used. The stage distance is L=50cm with viewing directions defined at 3, 6, 9, and 12 o'clock (0°, 90°, 180°, 270°).
• Response Time Testing (Figure 2): The LCD is switched between white (100% optical response) and black (0% optical response). The rise time (Tr) is defined as 10% to 90% luminance change, and the fall time (Tf) is 90% to 10% luminance change.

4. Application Guidelines & Critical Notes

Intended Use

• Compact embedded display applications requiring a small 0.96-inch TFT screen.
• Wearable devices, portable meters, smart home controls, and other small form-factor applications.
• Applications requiring a simple 4-line SPI interface for easy integration with microcontrollers.

Critical Design Considerations

1. 4-Line Serial SPI Interface: The module uses a 4-line serial SPI interface (typically CSX, SCL, SDA, D/CX). This is a simple, standard interface suitable for general-purpose microcontrollers.
2. Low Resolution (80×160): The low resolution (80×160 pixels) is ideal for simple icon-based GUIs or text displays. The host MCU must support this resolution in its display controller configuration.
3. Wide Input Voltage Range: VCC and IOVCC accept a wide range of input voltages (VCC: 2.5V to 3.7V, IOVCC: 1.65V to 3.7V). This allows for flexible power supply design. The VIH/VIL thresholds are based on IOVCC.
4. Backlight Driving: The backlight uses a single white LED requiring IF = 20mA at VF = 3.0V. A simple resistor or a small constant current source can be used.
5. Small Package: At 0.96 inches, the module is very small. The outline drawing shows a thin profile (BL thickness ~1.05mm). Mechanical mounting must be designed precisely to avoid stress on the glass or FPC.
6. Operating Temperature Range: The module supports an industrial temperature range: -20°C to +70°C (operating) and -30°C to +80°C (storage).
7. Display Type (TN): TN (Twisted Nematic) TFT technology typically has a limited viewing angle (e.g., 12 o'clock directional dependency). The viewing angle is optimized for a specific direction. Ensure the installation orientation aligns with the intended viewing direction.
8. Power Sequencing: Carefully follow the power on/off sequence suggested in the specification, particularly the RESX timing during sleep mode transitions.

Handling & Compliance

• ROHS Compliance: The module is ROHS compliant as noted in the outline drawing.
• Observe standard ESD precautions during handling and assembly.
• The module contains fragile glass and a thin FPC – handle with care.
• Do not attempt to disassemble or modify the LCD module.
• All NC (No Connect) pins should be left open.

5. Conclusion & Design-In Support

The LS096I04-S-V1 specification details a compact 0.96-inch TFT display module with an 80×160 resolution, a simple 4-line SPI interface, 262k color support, and a wide input voltage range — an excellent choice for small, cost-sensitive embedded display applications.

Key Strengths

• Ultra-Compact Size (0.96 inch): Fits in the smallest enclosures.
• Simple 4-Line SPI Interface: Easy to drive with any microcontroller.
• Low Power: Very low backlight current (20mA) and flexible core voltage.
• Wide Input Voltage Range: Simplifies power supply design.
• 262k Colors: Supports smooth color transitions for small graphics.

Main Design Focus

• The critical design task is simply interfacing the module via the 4-line SPI bus from any common microcontroller, configuring it to output an 80×160 RGB image.
• Supporting requirements: Provide a stable supply voltage within the 2.5V to 3.7V (VCC) and 1.65V to 3.7V (IOVCC) range. Provide a 20mA/3.0V source for the backlight LED. Ensure mechanical mounting correctly aligns with the small outline.

This module is an excellent choice for applications requiring a tiny, easy-to-drive TFT display for simple GUIs or status indicators.
