As for the LCD splicing screens currently used in China, most of them are assembled by LCD panels produced by Samsung, LG and BOE. However, due to technical reasons, BOE's domestically produced LCD panels are slightly lower than those produced by Samsung and LG in some respects. At the same time, LCD panels of the same size, same brightness, and same splicing have certain advantages in price. However, due to the high competition in the domestic LCD splicing screen market, especially the price competition is very chaotic, and some unscrupulous merchants often convert some LCD TV screens into LCD splicing screens to sell to customers in order to obtain greater profits, which further disrupts the LCD Splicing screen market. In order to facilitate the purchase of customers, Shenzhen Siyuan Video Technology Co., Ltd. has made the following introduction on how to distinguish between LCD splicing screens and TV screens, so that customers can be fooled when purchasing LCD splicing screens.
Method 1, distinguish from the perspective of ports.
Siyuan Video 55-inch LCD splicing screen adopts RGBBNC interface and professional DVI-D video interface, while LCDTV screen does not have BNC self-locking color difference input interface and DVI-D interface; and the LCD splicing screen can be controlled by S232 serial port, open control There are more than 200 kinds of passwords, and adapt to various industry environments. Although LCD TV screens can also be controlled by S232 serial port, they only have remote control commands and cannot achieve industry control.
The second part is to distinguish from the perspective of image resolution.
It is understood that the resolution of the LCD splicing screen can be adjusted automatically according to the user's display content, whether it is horizontal or vertical screens. Now the resolution of LCD splicing screen has reached 1920*1080p, which satisfies the user's display requirements to a certain extent. Moreover, the LCD TV screen only supports several resolutions specified in the manual, but when it encounters a display signal with a special resolution, the screen will be threaded. Therefore, when users distinguish between LCD splicing screens and LCDTV screens, they only need to use some signals of different resolutions for display testing.
Method three is to distinguish from the perspective of service life.
Compared with LCD TV screens, LCD splicing screens have obvious advantages in terms of appearance design, current consumption, applicable temperature, and anti-interference. LCD splicing screens have obvious advantages in terms of service life; LCD splicing walls usually need to be switched on for a long time, even 365 days of continuous use, while LCD TV screens generally only need to be used continuously due to the user group. If the LCD screen is turned on and used for a long time like an LCD splicing screen, the probability of failure will be very high. Therefore, when distinguishing whether the 46-inch LCD splicing screen is a real splicing screen panel, it only needs to be energized for a long time.
They are distinguished from the degree of color reproduction.
