LCD

I got myself a 7inch LCD cheap on Ebay thinking that it had a HDMI connector on it but it actually only has a ribbon connector which is described as a "LCD Interface 24-bit parallel".

7" Capacitive Touch 800*480 TFT TTL LCD Screen Display Module For HDMI | eBay

LCD Interface Definition

PIN NO. SYMBOL DESCRIPTION Type FUNCTION

1 VLED- Backlight negative input Backlight negative, connects to GND or PWM control

2 VLED+ Backlight Positive input Backlight Positive, 5V typical

3 GND Ground input Ground

4 VCC Power supply input Power supply, 3.3V

5 R0 Data lines input Red layer data lines

6 R1

7 R2

8 R3

9 R4

10 R5

11 R6

I was wondering if there was some kind of module I could get that would convert the HDMI signal back to the LCD signal. Any suggestions what to search for?
