Display
In this group, we can choose the parameters: size, resolution, touch, light, kind of.
Size:
Screen size is the size of the display of our device. Is given in inches (1 inch is approx. 2.54 cm). The higher the diagonal of this, of course, a larger display device. Available in tablets and data collectors are different screen size.
Resolution:
This parameter specifies the number of pixels in the image displayed on the screen in the current display mode, the image is made of pixels. Resolution is expressed as the number of pixels in the horizontal and vertical. Resolution level consists of a vertical line, while the horizontal lines vertically.
Standard on-screen resolution
Touch type:
Screen Resistance / Resistance
Touch-sensitive surface is made of two plastic plates. On the surface of the plate is a thin and scratch-resistant plastic. Is also coated with a thin layer of conductive material (tin oxide and indium oxide) placed on the bottom of "fast". At the upper long (i.e., below the conductive material), a second plastic plate. Both plates have no contact with each other until the user of the device does not press the screen with your finger or stylus. Contact occurs between spaced slightly screens. As a result of contact created a short circuit that by measuring the vertical and horizontal resistance is converted to data indicating the CPU contact area.
Screen resistive / resistive resistive screen provides good visibility, but that falls quite heavily in the sun. This type of screen, as opposed to capacitive screen, allows the use of ink (useful herein stylus). About multitouchu we can only dream of.
Capacitive screen
The capacitive touch generally consists of a fast-coated glass insulator (similar to that used in screens resistance). Touching the surface of the plate with a finger or other thing, conductive causes disruption in the flow of current. Next, place your finger from the screen interface is measured from the four corners of the screen.
Capacitive screen also provides decent visibility in the sun. We can only handle it with your finger or conductive materials. Is inconvenient in the winter, because we have to take off the gloves to be able to do anything on the phone (you can use special gloves). Some phones at subzero temperatures can go crazy and the screens do not read properly our gestures. This type of touch panel provides us with an unusual facility, which is to support multitouch technology.
Brightness:
The light emitted perpendicular to the surface of the glowing (and reflective). In this way, we describe the amount of light that is emitted from a particular area and the incident at a specific angle. This value is given in candelas per square meter (cd / m2).
Type:
Shiny matrix (glare)
It is the most common type of laptop screens due to the lower cost of production. A characteristic feature of this type of matrix is a mirror effect - sunny, clear days, the environment is reflected in the screen of the laptop.
Matt matrix
On the screen is covered with an additional layer (polarizer), which protects against the sun's rays rebounding. It works primarily outdoors on sunny days, when the owner of the device is exposed to intense light.
IPS
Matrices of this type are characterized by a very wide viewing angles horizontally and vertically, have uniform illumination and better color fidelity mapped. In conjunction with control systems that operate on a 12-bit color patterns and enable 16-bit color processing, and further supported by the DUE function, are the ideal solution for even the most demanding users, using them for professional use.
Gorilla Glass
It is chemically tempered glass with an alkali aluminosilicate. It is no secret, how it arises: the cure consists in immersing it in a hot solution of potassium nitrate (at a temperature of 400 degrees Celsius). This reduces potassium ions leave the surface creating a larger space for sodium ions, which Gorilla Glass "run through" is pressurized. When the glass cools, larger ions cure them.
Sunlight Readable
By using additional filters on the screen, which reflect sunlight the screen is more legible. This type of display is equipped with a protective outer layers of anti-reflective optical to eliminate the effect of sunlight glare.
