Introduction to B116XTB01.0 LCD Panel

B116XTN01.0 is a color active matrix liquid crystal display composed of a TFT LCD panel, a driver circuit, and LED backlight system. The screen features a 16:9 widescreen format with a resolution of 1366 × 768 (HD), supports 262K colors, and uses RGB 6-bit data drivers.

B116XTN01.0 is equipped with an LED backlight driving circuit, and all input signals are compatible with the LVDS interface, allowing it to connect to display systems that meet the corresponding electrical specifications. It is primarily designed for notebook-style personal computers and industrial equipment.

B116XTB01.0 Key Specifications

The table below presents the core specifications of B116XTN01.0.

Integrated Touch Panel Architecture (On-Cell Touch)

The B116XTB01.0 integrates capacitive touch functionality into its LCD module, enabling direct screen interaction without requiring a separate external touchscreen.

1. On-Cell Touch Structure and Advantages

B116XTB01.0 uses an On-Cell capacitive touch structure, in which the touch sensor is integrated onto the outer surface of the LCD's upper glass substrate, eliminating the need for a separate externally attached touchscreen.

l Reduced Thickness and Weight: Eliminates the additional touchscreen layer, helping create a thinner and lighter display module.

l Improved Optical Clarity: Reduces air gaps and bonding layers, helping minimize reflections and improve image clarity.

l Enhanced Structural Reliability: Reduces the risk of delamination and air bubbles, improving long-term stability.

2. Touch Operation and Interface Performance

l Touch Operation and Multi-Touch: Projected capacitive touch technology can support multi-touch input and gesture recognition, enabling responsive and intuitive interaction.

l Communication Interface: The touch controller IC typically communicates with the host through interfaces such as I²C or USB, depending on the module design.

3. Compatibility Checks for Replacement

When replacing or repairing the screen, verify the following aspects:

l Interface and Pin Configuration: Check whether the motherboard's touch FPC connector matches the required supply voltage and signal pin assignments, including SDA, SCL, INT, and RST where applicable.

l Drivers and Firmware: Ensure the host operating system, such as Windows or Linux, supports the touch controller's driver and communication protocol to prevent unresponsive touch input or inaccurate coordinate mapping.

eDP Interface and Pin Configuration

B116XTB01.0 features a 40-pin eDP (Embedded DisplayPort) interface for transmitting image data, making it suitable for compatible notebook computers and other display devices. The interface uses a single-lane configuration to meet the panel's image transmission requirements. Unlike LVDS, eDP uses a different signal transmission method, so the host interface type and signal configuration must be verified when replacing the screen.

The panel's logic circuit operates at a typical voltage of 3.3 V. During installation or replacement, carefully check the 40-pin connector's pin assignments, power pins, signal allocation, and cable layout to ensure compatibility with the motherboard.

The B116XTB01.0 module uses an internal printed circuit board assembly (PCBA) to efficiently manage signal processing and power distribution:

l Signal Processing and Display: External DisplayPort signals are decoded by the DP receiver and panel controller to generate control data, driving the gate and source driver ICs to produce a (1366×768)-pixel image.

l Power Supply and Gamma Circuit: The input DC power is regulated by DC/DC converters and the gamma correction circuit, providing precise voltage levels and grayscale signals for the panel and driver ICs.

l Backlight Driving: The LED power supply is regulated through boost conversion and current-balancing circuits to drive the LED strips and provide uniform backlighting.

Power-On/Off Sequence & Timing Requirements

Proper power sequencing is essential to prevent screen flickering, white screens, abnormal display artifacts, and potential damage to the LCD or touch controller.

Power-On Sequence

First, power on the 3.3 V logic supply (VDD)). Once stable, reset the touch controller and initialize its logic. Then enable eDP image data transmission through the Main Link and AUX channels. Finally, activate the backlight enable signals (BL_EN/PWM) after the image stabilizes.

Power-Off Sequence

Follow the reverse order. Disable the backlight first, then stop eDP image transmission and reset the touch signals. Finally, turn off the (VDD) logic supply.

Handling Precautions

1) Avoid scratching the front polarizer. Clean with a soft, absorbent cloth.

2) Turn off the power before connecting or disconnecting cables.

3) Wipe off water immediately to prevent discoloration or spots.

4) Handle the glass panel carefully to avoid drops, impacts, or breakage.

5) Prevent electrostatic discharge (ESD) by grounding yourself during handling.

6) Do not open or modify the module assembly.

7) Do not press the rear reflector sheet.

8) Insert or remove signal connectors without twisting or tilting them.

9) Avoid bending or twisting the module during installation or use.

10) Ensure the power supply meets applicable Limited Power Source (LPS) requirements.

11) Disconnect power before handling. Do not touch electrodes, cables, connectors, or LED backlight circuits.
