  • The HP L5006tm Touchscreen.

    Hi im a NB. I've been looking and reading alot on this forum in the past week. I've also did some searching on my own for touchscreens. This forum has been really helpful! I'm glad that theres something like this.

    Well ive done a search and I did not come up with anything about this , HP L5006tm Touchscreen... I want a 15" or 10" screen so i can mold it into my dash.

    I also noticed about the resolution thing, and screens having a native resolution. Can someone explane this to me? This screen has a 1024 x 768 native resolution. From what I gather its what resolution I can run the screen at and it still be clear correct?

    The veiwing angle says, Image Max H-View Angle 120, and Image Max V-View Angle 100. The H means horizontal, and the V means vertical? 100 and 120 being Degrees correct?

    I do alot of car custom work, but im just geting into the car PC stuff.

    Thanks for any input. I have seen alot of replys and I have to say that I am verry impressed with the knowlage here! The knowalge here surpasses me at the moment!

    I also have a link to the screen at the best price I found...

    Thanks again!

    About native resolution: Back in the old days (like ten years ago, heh), people used CRT monitors (big, tv-style boxes). A CRT works by scanning a beam of electrons across a phosphorus coated surface; The surface lights up as the beam hits it, and the beam scans fast enough that it looks like a picture (it scans from left to right and from top to bottom of the display, and does one line of the image at a time, moving down to each line in the image in turn) . One advantage of this older technology is that you can control how fast the beam scans, and how much information you put on the beam. Thus, you can change a CRT monitor's resolution up and down, to suit your application, with basically no visible ill effects.

    Today's flat-panel monitors are different. They typically use a grid of dots (pixels) on a panel that lays on top of a light source of some kind. Each pixel on the grid can change its properties, allowing whatever color light to pass through you want, by changing the sort of electrical signal you send that pixel. They don't scan an image onto the screen like a CRT, they display it all-at-once. This technology has many benefits (thin sizes are possible, low power needed compared to CRT), but one of the drawbacks is that you can't change the number of pixels in the image (the resolution). You can send the display images that are at a different resolution, but the electronics in the display will simply scale the image so that it fits the resolution of the panel. Trouble is, this scaling almost never works out to look as good as running the display at the "native" resolution, even if the picture you are scaling is the same shape as the monitor.

    One thing you might note, if you've shopped for a high-def television lately, is that a lot of the sets advertise "1080p". This relates to a scaling issue...the resolution of such displays is 1920 X 1080, which happens to be a good match for broadcast hi-def television and video sources like HD-DVD and Blu-ray disc players. Still, manufacturers spend a lot of money and effort coming up with better ways to scale images. A lot of development effort is spent on scaling DVD images to fit high-res displays, which you can see when you price "upconvert" DVD players against regular DVD players.

    Going to your monitor's specs, 1024 X 768 is a very common resolution in computer displays, and I can't imagine a scenario where this resolution isn't available for your graphics card to use to drive the monitor. The 400:1 contrast ratio is pretty run-of-the-mill. I don't see anything on the readability in sunlight of this display; I would assume, as with most screens used in this application, that you will have problems with glare in the sunlight. There are some industrial displays that are made to be sunlight readable, but they tend to be very expensive. You should be able to use some of those customization skills to mitigate the glare, tho.
    I have too much time and too little aggravation in my life, so I built a carPC. ;)

      Thanks for the reply! That clears up alot.

      So this seems to be a good screen for the size/money/stats go correct? I know i dont see anything like this on the forum here, and i know you guys got this stuff down pat.

      It shouldnt be anyless glare resistant then the other screens that are not sunlight readable right?
