Tcon LCM Gold Finger Pcb Design 3mils 6 Layer Rigid Flex Board HDI PCB

12Layer Rigid-flex HDI PCB for Tcon LCM / Soft gold finger

The TCON (timing controller) board translates between a standard video signal and the specific row and column driver signaling needed by a specific LCD (or other) panel.

An LCD panel is like a CRT in the sense that there is a chemical which responds optically to an electric charge, and that charge must be refreshed or else the optical response decays. The panels themselves have precision timing requirements needed to refresh the LCD chemistry at the proper rate to keep the signal uniform and avoid decay or update.

1.Generation of T-con

The gold finger material Polymide is thin and flexible. Other areas material CCL FR4.

2 . Specifications:

In TV video timing, you can have a video signal between 24 and 60 frames per second, and many different resolutions, but the panel itself only supports a single resolution and timing. The timing is extremely precise and the distance of the cables from the timing controller to the panel need to be very precise. This is why the panels come from the panel manufacturer with the TCON pre-attached and wired. The TV or monitor manufacturer then designs their own PCB with TV/PC inputs, tuner, audio, speaker, etc., and the video signal transmits to the TCON board over a standard interface such as LVDS, VX1, or eDP. The TV maker designs one board which can then support many panel sizes, and can even use the same board with both LCD and OLED. Some TCON boards have 60 Hz to 120 Hz frame rate converters, but this isn’t very common any longer, as the TV System on chip usually handles this these days.
