11 inch lcd screen free sample

Testing out LCD boards for students to use as "scratch paper" during exams. We"re using dry-erase whiteboards for most of the students, but needed an alternative for lefty/ lefties (left-handed students) because their palms would smudge/erase the marker from the whiteboards.

This one (red tablet on the right side) writes smoothly and easily. Is fairly legible. The orange tablet on the left side is another manufacturer"s LCD board. This one (red) does NOT have a lock feature to keep from accidentally erasing. It does include a nice little neoprene type sleeve. The backside of this tablet looks unfinished. Overall, feels pretty cheap, and to be fair, it"s not terribly pricey (purchased at $14.99 plus tax). Red tablet shipped w/ some nice extras: 2 adhesive magnetic strips (so you could potentially hang on fridge), and a tiny screwdriver, which I"m assuming would be for replacing battery eventually.

Many Apple products use liquid crystal displays (LCD). LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a corresponding transistor responsible for turning that subpixel on and off.

Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD panel used in the iMac (Retina 5K, 27-inch, 2019) has a display resolution of 5120 x 2880, which means there are over 14.7 million pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 44 million individual picture elements on the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off (dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.

In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store.
