Driver PCB for LCD Panels - Specifications and Selection Guide

Product Specifications

Technical details and manufacturing context for Driver PCB

Definition

A Driver PCB is a specialized printed circuit board that serves as the electronic interface between the main controller and an LCD panel. It receives digital video signals and control data from the main controller via standard interfaces such as LVDS, eDP, or MIPI. The board processes these signals through timing controllers (T-CON) and driver ICs, converting them into precise voltage levels and timing sequences required to charge and maintain the liquid crystal cells in the LCD panel, thereby controlling light transmission through each pixel. This component is essential for the proper functioning of LCD displays in various applications, including computer monitors, televisions, and industrial equipment. The Driver PCB is manufactured using FR-4 substrate with copper traces, solder mask, driver ICs, and passive components such as resistors and capacitors. It is available in custom sizes, with board dimensions typically ranging from 100 to 200 mm. Operating voltage is typically 3.3 to 5 V DC, and power consumption ranges from 0.5 to 2 W depending on panel size and resolution. The board operates within a temperature range of -20 to 70 °C, with storage temperature from -40 to 85 °C, and relative humidity of 10 to 90% non-condensing. Ingress protection ratings vary from IP40 to IP65 depending on the enclosure, per IEC 60529. PCB material is FR-4 per IPC-4101, with copper thickness of 1 to 2 oz (1 oz standard, 2 oz for high current) per IPC-6012. Surface finish options include HASL to ENIG, with ENIG for fine pitch, per IPC-6012. Minimum trace width is 0.1 to 0.2 mm, and minimum hole diameter is 0.2 to 0.3 mm, per IPC-2221. Board thickness is typically 1.0 to 1.6 mm (standard 1.6 mm) per IPC-6012. Weight ranges from 50 to 200 g depending on size and layer count. All values are reference ranges and must be verified with the legal manufacturer or supplier for the specific model and application.

Working Principle

The Driver PCB receives video data and control signals from the main controller via interfaces like LVDS, eDP, or MIPI. It processes these signals through timing controllers (T-CON) and driver ICs, converting them into precise voltage levels and timing sequences required to charge and maintain the liquid crystal cells in the LCD panel, controlling light transmission through each pixel.
