Can two LVDS LCD panels with the same connector be interchanged?

Not automatically. Connector type alone does not confirm compatibility. Compare supply voltage, pin assignment, channel count, JEIDA or VESA mapping, color depth, timing, backlight circuit, outline and connector position.

What is the difference between 6-bit and 8-bit LVDS?

The terms normally describe panel color data depth and the required transmitter or receiver mapping. The host, cable and LCD timing controller must support the exact bit depth and JEIDA or VESA format specified by the panel.

Can HDMI connect directly to an LVDS LCD module?

No. HDMI and panel-level LVDS are different interfaces. A controller board matched to the LCD resolution, timing, voltage, pinout and backlight is required.

Does LVDS also carry the touch-screen signal?

Usually not. LVDS carries display image data. PCAP touch commonly uses USB or I2C, while resistive touch requires a separate touch controller or analog interface.

What information is required for an LVDS LCD quotation?

Send the existing panel model or drawing, size, resolution, LVDS mapping and pinout, brightness, touch and optical requirements, operating temperature, host interface, sample quantity and annual quantity.
