3.2.2 MIPI DSI Characteristics (DC)
The specification defines the MIPI DSI DC characteristics for both LP (Low-Power) and HS (High-Speed) modes. Key parameters from the specification include:
| Item | Symbol | Test condition | Min. | Typ. | Max. | Unit |
|---|---|---|---|---|---|---|
| LP-RX: Logic 0 input voltage | VIL | VDDIO=1.70V~1.90V | -50 | - | 550 | mV |
| LP-RX: Logic 1 input voltage | VIH | VDDIO=1.70V~1.90V | 880 | - | 1350 | mV |
| LP-TX: Thevenin output high level | VOH | VDDIO=1.70V~1.90V | 1.1 | 1.2 | 1.3 | V |
| CD-RX: Logic 0 contention threshold | VILCD | VDDIO=1.70V~1.90V | - | - | 200 | mV |
| CD-RX: Logic 1 contention threshold | VIHCD | VDDIO=1.70V~1.90V | 450 | - | - | mV |
Note: The expected operating condition for VDDIO is shown in the table as 1.70V~1.90V. The I/O leakage current (ILEAK) when Vin=-50mV~1350mV is -10 to 10 µA. The output impedance of the LP transmitter (ZOLP) is ≥ 110 Ω at VDDIO=1.80V.
3.3 Display Timing (Video Mode)
The specification includes diagrams for Display Timing in Video Mode, showing the relationship between VSYNC, HSYNC, Data Enable (DE), and pixel data. The timing parameters described in the diagram are:
- Vertical Sync (Vsync): Visible image, Vertical Back Porch (VBP), Vertical Front Porch (VFP), and Vsync pulse width.
- Horizontal Sync (Hsync): Horizontal Back Porch (HBP), Horizontal Front Porch (HFP), and Hsync pulse width.
- Data Types: The diagram shows Data Types (DT) such as 01h (Vsync Start), 21h (Hsync Start), 09h (Blanking Packet), and 3Eh (RGB data).
- DSI Clock (DSICLK): Referenced as the timing reference for one line period.
Note: The exact numerical timing values (e.g., number of lines for VBP, number of pixels for HBP) are not provided in the snippet. These must be derived from the full specification or configured according to the driver IC's requirements for a WQXGA (2560x1600) resolution panel.
4. Application Guidelines & Critical Notes
Intended Use
- High-resolution 10.1-inch display applications, such as tablets, high-end portable monitors, and industrial equipment requiring fine detail.
- Systems using a standard MIPI DSI interface with dual-port, 4-lane configuration for high bandwidth.
- Applications requiring a high pixel density (300 PPI) display with a 16:10 aspect ratio.
Critical Design Considerations
- MIPI DSI Dual-Port (4-Lane): The module requires a MIPI DSI host with two ports (Left DSI and Right DSI), each with 4 data lanes and a clock lane. The total bandwidth requirement for driving 2560x1600 @ 60Hz is significant and must be supported by the host processor.
- Multi-Rail Power Supply: The module requires a dual-rail analog power supply (VSN and VSP) in addition to the digital I/O supply (VDDIO). The typical VDDIO voltage is 1.8V. An external power management IC (PMIC) capable of generating these voltages is required.
- External Backlight Driver Required: The module provides direct access to the LED anode (LED_A) and cathode (LED_K) pins. This requires an external constant-current LED driver circuit to power the backlight. The number of LEDs and their configuration (series/parallel) are not explicitly stated in the snippet, so the driver must be designed to accommodate typical 10.1-inch panel LED strings.
- High Resolution (2560x1600 @ 16:10): The module offers WQXGA resolution, which requires high bandwidth on the MIPI DSI bus. Careful PCB layout and impedance matching (100Ω differential for MIPI lanes) are critical to maintain signal integrity.
- VSYNC (Tearing Effect) Output: Pin 36 provides a Tearing Effect output signal (VSYCN) from the Right DSI port. This signal can be used by the host to synchronize frame updates and avoid tearing artifacts.
- Power-On/Off Sequence and Reset: The specification mentions a RESET signal (Pin 1). Proper power sequencing (power supplies stable before releasing reset) and a hardware reset sequence must be implemented to ensure reliable driver IC initialization.
- Mechanical Profile: The module size is 221.85 × 145.15 × 3.3 mm. The FPC connector (FH34SRJ-40S-0.5SH(50)) is a 0.5mm pitch, 40-pin connector. Ensure the mechanical design provides adequate clearance for the FPC bend radius.
- Operating Temperature: The operating temperature range is not explicitly provided in the snippet; however, typical industrial TFT-LCD modules operate from -20°C to +70°C. Verify the full specification for this parameter.
Handling & Compliance
- Observe standard ESD precautions during handling and assembly.
- The module contains fragile glass – handle with care. Avoid mechanical stress on the active area or FPC connector.
- Do not attempt to disassemble or modify the LCD module.
- All NC (No Connection) pins should be left open.

- Supporting requirements: Ensure the host processor and MIPI DSI transmitter can support the necessary bandwidth for WQXGA resolution (2560×1600 @ 60Hz or intended refresh rate). Provide a well-regulated 1.8V supply for VDDIO. Design a secure mechanical housing to protect the module during operation.
This module is a formidable choice for engineers designing premium products requiring a high-resolution, high-quality display in a standard 10.1-inch form factor with a standard high-speed MIPI DSI interface.
