I downloaded the spec sheet for an Optrex 10.4" TFT panel - Apollo
Displays can provide this and other LCDs with built in touch screen
for around $250 - and the signals required on the 31 pin connector
are:
1 - GND
2 - DCLK <- This signal is not currently present and Jesse Off at
T.S. would need to generate this on another pin.
3 - HD < HSync
4 - VD < VSync
5 - GND
6 - R0
7 - R1
8 - R2
9 - R3
10 - R4
11 - R5 <- Connect to 0V (GND)
12 - GND
13 - G0
14 - G1
15 - G2
16 - G3
17 - G4
18 - G5 <- Connect to 0V (GND)
19 - GND
20 - B0
21 - B1
22 - B2
23 - B3
24 - B4
25 - B5 <- Connect to 0V (GND)
26 - GND
27 - DENA <- This signal is not currently present and Jesse Off at
T.S. would need to generate this on another pin.
28 - VCC (3.3V)
30 - GND
31 - SC <- Scan direction control (Low=Normal, High=Reverse) would be
connected to either 3.3V or GND depending on installation.
There is a note saying HD and VD are not being used for timing
control, and looking at the timing it's all being done with DENA
(Which goes low during each vertical scan and high between scanlines)
and DCLK (which clocks each pixel), so Jesse Off should be able to
map DENA and DCLK onto the HSync and VSync lines and then a couple of
simple 3.3V buffers and connector would allow a the Optrex panel to
be connected directly to the TS-7300...
For desktop use this does not save you any money as you can buy 10.4"
LCD panels with touchscreen (USB) for less than the bare Optrex
panel, but EarthLCD want $600 for an Industrial 10.4" touch panel,
and therefore adding the TFT directly to the TS-7300 (with the simple
interface card) would save a fair amount of money.
Hope this helps,
