An LCD Screen's Column Board (A Closer Look At A Notebook LCD Screen)
The timing controller is attached to the column board. The column board is unscrewed and folded over the top of the screen so that you may view the important parts of the column board. The timing controller is a chip which supplies the control and video signals.
The timing controller receives video signals. These signals are already compatible with the resolution of the notebook LCD screen. The video signals that the timing controller receives are created by the graphics controller circuitry.
The backlight is what generates the light that you see when you view your display. The backlight is powered by the inverter. The cable that plugs into the inverter is also shown here
The flex connecters connect the column board to the inputs of the data drivers and scan drivers on the glass of the notebook LCD screen. The control signals which are sent to three screen drivers are sent down the right side of the notebook LCD panel.
The sticker on the back of the notebook LCD will also reveal the OEM number or assigned part number. These numbers are helpful when determining a replacement panel for a notebook.
