parallax lcd display factory

The Parallax Serial LCDs (liquid crystal displays) can be easily connected to and controlled by a microcontroller using a simple serial protocol sent from a single I/O pin. The LCD displays provide basic text wrapping so that your text looks correct on the display. Full control over all of their advanced LCD features allows you to move the cursor anywhere on the display with a single instruction and turn the display on and off in any configuration. They support visible ASCII characters Dec 32-127). In addition, you may define up to eight of your own custom characters to display anywhere on the LCD. An onboard piezospeaker provides audible output, with full control over tone note, scale and duration using ASCII characters Dec 208–232.

The LCDs currently for sale are updated to Revision F. Basic functionality remains the same, but power requirements and the layout of the backpack have changed. Please see the documentation for information on your model.

This device can be connected to a PC serial port using a MAX232 line driver. The circuit isn’t supported by Parallax, but it’s possible to make this connection with a few extra parts.

I don"t know how to properly initialize the screen. So, it can sometimes take a few writes to the display to get it sorted out, so I got around this by just printing "initialize" a few times before I started printing data.

Since our brain is used to taking two 2D images and combining them to make a 3D model for us, it should be easy enough to persuade it to do so with any two images displaying the expected degree of binocular disparity. Mercifully for b-movie film producers and, more recently, LCD display manufacturers, it turns out that it is actually very easy to fool the brain like this.

The problem for computer screen and TV manufacturers, then, was to create a plausible 3D image without using specs or - as with early attempts, two separate screens. Sharp, along with most other display companies, started looking into developing a 3D display some time ago: the company"s European lab began its research back in 1992. Dimension Technologies Inc (DTI) meanwhile began its research in the mid 80s and now holds several patents covering technology for switchable 2D/3D screens.

Early prototypes consisted of double screen systems but by 1994 Sharp"s researchers managed to get it down to one panel. The next trick to crack was a screen that could display both 3D images and 2D images: all but the most frighteningly dedicated gamers would be reluctant to have a set up that meant changing monitors just to check email.

In a simple 3D screen, a very fine grating, called a "parallax barrier", is placed in front of the LCD screen. It does the job of the polarising glasses, directing light from each image slightly differently so that at a so-called "sweet spot" about 20 inches in front of the screen the two images are separated just enough that the brain will create a composite 3D image. The downside of this is that since the parallax barrier is a permanent feature of the monitor, then it"s always in 3D mode - not much use for day-to-day use, as noted above.

In Sharp"s screen, the parallax barrier is created by a second LCD screen - known as the "switching" LCD - which is off in normal 2D mode. When this screen is activated, it polarises in stripes so that it is impenetrable to light from the first LCD screen, generating opaque grid lines in front of the normal screen. The following graphic is from Sharp"s background to the process:

The limiting factor on this method is that you have to have your head in exactly the right spot to see the 3D image, so no peering over shoulders allowed. Multiple viewer screens are not much more complicated to make: the parallax barrier is finer and cross hatched instead of striped. However, making the images for such a screen is much harder, since instead of two pictures, the 3D image is created by combining at least four viewpoints.

And since they support switching electrically between flat display (2D) and three-dimensional display (3D) modes, they can be used in new products optimized for 3D content as well as for applications where conventional LCDs are presently used.

For example, a 3D LCD computer monitor could display word processor and spreadsheet files in the 2D mode while employing the 3D mode for computer graphics and games.

This new type of display device makes possible a range of new applications providing three-dimensional images with an enhanced level of visual ambience.

The distance between the human eyes is about 65 mm, and the images seen by the right and left eyes are always slightly different (binocular parallax).

We develop, design, manufacture, and sell displays where it is necessary for the interface that deliver a lot of information at an instant and deliver it to the global market. We create interactive spaces that go beyond the expected, elevate everyday lives, and move people"s hearts. From bases in major cities in Asia, Europe, and North America, we build strong customer relationships by developing products that respond to market needs.
