![]() Brightness: The amount of light emitted from the display.Displays with fast response times can make better transitions in displaying moving objects without unwanted image artefacts. A display with slow response times displaying moving pictures may result in blurring and distortion. For an LC display it is defined as the total time it takes for a pixel to transition from black to white, and then white to black. Response time: The time it takes for the display to respond to a given input.Projection displays that use three monochrome CRTs do not have a dot structure, so this specification does not apply. In the case of CRT based displays, pixels are not equivalent to the phosphor dots, as they are to the pixel triads in LC displays. A smaller dot pitch generally results in sharper images because there are more pixels in a given area. It can be measured as the horizontal or diagonal length of a pixel. Dot pitch: This is the size of an individual pixel, which includes the length of the subpixels and distances between subpixels.In general a higher resolution will yield a clearer, sharper image. Display resolution: the number of pixels in each dimension on a display.Display size: the diagonal length of the display.The following are important factors for evaluating television displays: ( July 2009) ( Learn how and when to remove this template message) Unsourced material may be challenged and removed.

A large-screen TV requires a longer tube, making a large-screen CRT TV of about 130 to 200 cm (50 to 80 in) unrealistic. ![]() The diagonal screen size of a CRT television is limited to about 100 cm (40 in) because of size requirements of the cathode-ray tube, which fires three beams of electrons onto the screen to create a viewable image. Large-screen technologies have almost completely displaced cathode-ray tubes (CRT) in television sales due to the necessary bulkiness of cathode-ray tubes. Recent technologies like organic light-emitting diode (OLED) as well as not-yet-released technologies like surface-conduction electron-emitter display (SED) or field emission display (FED) are in development to replace earlier flat-screen technologies in picture quality. Various thin-screen technologies are being developed, but only liquid crystal display (LCD), plasma display (PDP) and Digital Light Processing (DLP) have been publicly released. Prior to the development of thin-screen technologies, rear-projection television was standard for larger displays, and jumbotron, a non-projection video display technology, was used at stadiums and concerts. Large-screen television technology (colloquially big-screen TV) developed rapidly in the late 1990s and 2000s. ![]()
