A pixel (picture element) is the smallest piece of information in an image. Pixels are normally arranged in a regular 2-dimensional grid, and are often represented using dots or squares. Each pixel is a sample of an original image, where more samples typically provide a more accurate representation of the original.

The intensity of each pixel is variable in color systems, each pixel has typically three or four components such as red, green and blue, or cyan, magenta, yellow and black.

4．  What is Screen Resolution

The Resolution of a SANSUI television or display device is the number of distinct pixels in each dimension that can be displayed. The displayed resolution is controlled by all different factors in cathode ray tube (CRT), flat panel or projection displays using fixed picture-element (pixel) arrays.

It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels

Televisions are of the following Resolutions as follows : 

Standard-definition television (SDTV) :

l  480i (NTSC standard uses an analog system of 486i split into two interlaced fields of 243 lines)

l  576i (PAL, 720 × 576 split into two interlaced fields of 288 lines)

Enhanced-definition television (EDTV) :

l  480p (720 × 480 progressive scan)

l  576p (720 × 576 progressive scan)

High-definition television (HDTV) :

l  720p (1280 × 720 progressive scan)

l  768p ( 1366X768  progressive scan)

15． Why does my newly purchased flat-panel TV, the Portrait deformed and cannot be watched normally

1)  This phenomenon is not caused by the malfunction of the TV itself. It is due to the fact that most ordinary TVs currently receive 4:3 analog signals, but all flat-panel TVs now use 16:9 screens, different signal ratio and display ratio caused this issue. But usually, 16:9 screen TV will also have other image modes, such as program source mode, which displays the received signal in the same proportion, and the display ratio depends on the program source. That is, if the program source is 4:3, it will display 4:3; if the program source is 16:9, it will display 16:9.The image distortion phenomenon of flat-panel TVs is mainly because the display format is 16:9, which is different from the 4:3 of ordinary color TVs. The main reason is that the display screen is made with a 16:9 aspect ratio, so the image effect is relatively flat and people will change fat. Tablets generally rarely shifting. You can check the  image aspect ratio mode on the remote control if it is zooming in, if yes, there will be a phenomenon that the image is enlarged to that the logo can only be seen halfway or not. You can adjust the display format to 16:9.
