The LCD splicing screen in the market a wide range of applications, it is very high scientific and technological content of electronic products to enter the market in a relatively short time, the LCD splicing screen for the user is new product, or many users in use at the same time but to know very little, with the domestic LCD splicing market cohabitation, product quality uneven, for the user to buy the high price of LCD splicing screen caused by a certain degree of difficulty, the following five parameters can identify the pros and cons of the LCD splicing screen.

Parameter 1: support resolution

Resolution is one of the important parameters to measure the display effect of the display screen. LCD screen display screen clarity, the picture is delicate and other features are determined by the resolution of the. Currently on the market of large screen splicing is relatively high resolution, common are: 1366*768 and 1920*1080, if the resolution is too low, then do not choose.

Parameter two: contrast

The display of the color of the display screen and the effect of color display by the contrast of the decision. Currently on the market, the common contrast of LCD splicing screen is 3000:1, this contrast is relatively high. If the stitching screen contrast is not high, it will lead to the screen display screen color is not bright enough and rich.

Parameter three: brightness

The brightness of the screen displayed on the large screen of the liquid crystal splicing is determined by the brightness of the liquid crystal splicing unit. If the brightness is not high enough, it will lead to a strong light environment can not see the screen displayed on the screen. This can be based on their own needs to choose, such as the need to use in a strong light environment is high, the use of indoor environment can choose low brightness.

Parameter four: splicing gap

The splicing screen is made up of a plurality of mosaic panels, so there is a gap between the various panels. Stitching gap is too large will not only affect the appearance of the United States, but also the display of its effect also have a greater impact.

Parameter five: input signal type

If the large screen only supports a single signal type of input and output functions, in many places the use will be limited to support a variety of signal format input and output is more convenient to use.
