The ILI5960D is a specialized gate driver IC used to control the gate lines of TFT LCD panels. It sequentially outputs high-voltage pulses triggered by a start pulse, synchronized with a clock signal. This IC ensures precise pixel addressing vital for high-quality LCD display operation, making it a cornerstone for display modules supplied by companies like Panox Display.   Also check: Micro OLED

How Does the ILI5960D Gate Driver IC Operate in TFT LCD Panels?

The ILI5960D operates by receiving a start pulse (STVR) synchronized with a clock input (CPV). At each rising clock edge, a high-voltage pulse shifts to the next gate output line in the sequence. This mechanism drives the TFT gates sequentially, enabling pixel rows on the LCD panel to be activated accurately. The IC supports bi-directional shift control via the RL pin and allows dot expansion by cascading multiple ICs.

This sequential pulse shift process is essential for refreshing the display pixels efficiently, ensuring stable image quality and reducing power consumption in LCD modules used by Panox Display.

What Are the Key Features and Pin Functions of the ILI5960D?

Key features of the ILI5960D include:

• Up to 960 output gate channels, selectable using MODE1 and MODE0 pins.

• Bi-directional shift register controlled by the RL pin.

• High voltage CMOS technology in a COG (Chip-On-Glass) package.

• Output Enable (OE) pin to quickly disable outputs by pulling them to low voltage (VEE).

• Cascade function for driving large displays by linking multiple ICs.

Important pins and their functions:

Understanding these pins is critical for integrating the ILI5960D into an LCD system, especially in custom display solutions provided by Panox Display.

Why Is Precise Timing Important in the ILI5960D Gate Driver Application?

Precise timing of the STVR, CPV, and OE control signals is vital to ensure seamless data shifting and proper gate activation. Incorrect timing can cause flickering, incomplete pixel activation, or damage to the LCD panel. The datasheet specifies timing parameters governing the minimum pulse widths, setup, and hold times to maintain synchronization with the source driver IC (e.g., ILI6126C).

Proper timing guarantees the accurate and efficient operation of the display system, maintaining high image quality and longevity of TFT panels used in Panox Display’s advanced modules.

Which Applications Commonly Use the ILI5960D in Display Systems?

The ILI5960D is primarily used in high-resolution TFT LCD panels requiring extensive gate line control, such as industrial, automotive, and wearable displays. It commonly pairs with source driver ICs like the ILI6126C to handle both gate and source line driving functions, forming a complete driving solution.

Panox Display incorporates the ILI5960D in custom TFT LCD solutions spanning various industries, including optoelectronics, military instrumentation, and virtual reality devices.

How Does Cascading Multiple ILI5960D ICs Enhance Display Panel Size?

Cascading allows multiple ILI5960D IC chips to be linked in series via their outputs and control signals, enabling a single controlling source to drive larger display panels requiring more than 960 gate lines. The cascade function supports seamless data propagation and synchronization across chips to maintain uniform gate voltage driving.

This scalability offers flexibility to Panox Display customers who require large-format or special-shaped LCD modules for complex display demands.

What Electrical Characteristics Should Engineers Consider for the ILI5960D?

The electrical characteristics include absolute maximum ratings, recommended operating voltages, current consumption, switching frequency limits, and input logic levels. Some key specifications are:

Observing these ensures reliable operation and prevents damage, a step Panox Display’s engineers carefully validate during display module development.

When Should the Power-On and Power-Off Sequence be Followed for the ILI5960D?

The power-on and power-off sequence is crucial to avoid damage to both the driver IC and thin-film transistors in the panel. Typically, high voltage supplies (VGH and VEE) are applied after digital power rails (VDD and VSS) stabilize and removed before them during power down.

Following this sequence ensures controlled voltages on the gates and prevents transient stress. Panox Display provides detailed guidance on this in their custom module documentation to help customers avoid interface issues.

How Does Bi-Directional Data Shifting Influence Display Control?

The RL pin selects whether gate lines are driven from left to right or right to left (or up/down, depending on panel orientation). This flexibility allows different panel configurations and can optimize layout and driver routing.

Bi-directional shifting controlled via RL enables Panox Display to tailor driver IC configurations to suit a variety of TFT LCD designs and form factors.

Where Does the ILI5960D Fit Within the Overall TFT LCD Driving Architecture?

The ILI5960D acts as the gate driver stage complementing source driver ICs responsible for column data lines. It mainly manages the horizontal scanning of rows, enabling proper pixel addressing by activating the correct row electrodes sequentially.

Panox Display includes the ILI5960D as a standard component in many of their TFT LCD modules, integrating it alongside source drivers and controllers to provide a turnkey solution.
