Thread: Perfect 7" widescreen LCD?

I've been doing research on what type of an LCD might be the best for my application, and I've been picky about what I want - widescreen, high resolution (800x480 or 800x600), high brightness, and preferably a VGA or LVDS interface.

Most of the screens I looked at were either too big (8.4"+), too small, (~6"), were too low of a resolution (640x480), or were video-only (not VGA/LVDS).


I didn't want to have to take a Xenarc or a Liliput and tear it apart to get the bare LCD and parts, and I didn't want to have to get a kit (like DWW's).


I found this 7" LCD from Toppoly:

http://www.toppoly.com/toppoly/Product/TD070WGCB1.asp

Features:

• Wide VGA resolution (854x480)

• Supports NTSC/PAL/SECAM TV and VGA standard (possibly LVDS?)

• Supports picture rotation in U/D and L/R directions

• High brightness (420 cd/m2)

• Aspect ratio (16:9)

The System Block Diagram link above (1st of 3) seems to indicate that the LCD might have a LVDS interface.


The company's web site indicates that sample quantities are available, and production is set for right around now.


I have no idea how much they're asking, or whether they'll sell, but the specs look highly interesting.

Any thoughts?

I think we need price!

That LCD looks nice.
I'd buy it if the price is right.

I sent an e-mail to a sales person at the company, which is in Taiwan.

I'll see what they say about sales, pricing, and any technical specifications, if any.

Since it's a new product, they may be working on getting US distributors, so that may be an option.


Most of the other 7" widescreen LCD's I've seen have a much lower resolution, listed as 1440x230, but in reality it's physically 480x230.. way too low.


We'll see, I'll keep things updated here.

Just tacking myself on here to keep updated. :] Nice find.

This company has the LCD listed:

I sent them an e-mail inquiry about sample quantity availability..

this screen looks good if its not to expensive....

has anyone found a 7inch transflective tft pannel? if they have id definatly buy one - as the screen would only get more readable with direct sunlight..........

Has anyone found a price. It would need a touch screen overlay kit but that is no biggy

The fact that this is a fairly new model of LCD (production set for Q1-2004, or around now), it may be some time before LCD distributors will carry it, and hence, a lack of posted prices.


I'm waiting on replies from Toppoly themselves, and LCDInline, mentioned earlier.

Also, a LCD from Sharp with similar specs:

LQ070Y5DG02
7" diagonal
800 x RGB x 480 dot format
0.195 x 0.174 pixel pitch
156.0 x 83.3 viewable area
6-bit digital RGB input system (lvds, 18-bit?)
6-bit digital (lvds, 18-bit?)
1 CCFT backlight
380 NITS / cdm/2
4700 milliwatts consumption (4.7 watts?)
193.3 x 116.5 x 8.8 overall dimensions (mm)

From spec sheet:
http://sharp-world.com/products/devi...table/006.html

I believe this is also a relatively new model as well.


Edit again:

This place lists the LCD's, but they won't sell to individuals:

If you go to to request info, they have:

"Regrettably, we cannot support small quantity inquiries from INDIVIDUAL users for personal use."
