Outdoor LCD splicing screen

Abstract

The invention discloses an outdoor spliced liquid crystal screen. The spliced liquid crystal screen comprises spliced liquid crystal screen bodies, wherein high-transparency protective glass is arranged on the panel outer layers of the spliced liquid crystal screen bodies; gaps between the panels of the spliced liquid crystal screen bodies and the high-transparency protective glass are filled with sticky flexible glue; the main material of the sticky flexible glue is crosslinked polysiloxane. The periphery of the outdoor spliced liquid crystal screen is coated with protecting strips; the whole screen can be installed in a full-closed cabinet at a constant temperature. The outdoor spliced liquid crystal screen can be normally displayed out of door or when the ambient brightness is relatively strong, in addition, not limited by severe service environment such as high temperature, rain or snow. The outdoor spliced liquid crystal screen is long in the service life and beneficial to promote and apply in a wide range.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to an outdoor liquid crystal splicing screen that can display normally outdoors or under conditions of relatively strong ambient light brightness. Background technique [0002] At present, the common LCD splicing display panels in the market, such as Samsung, LG, AUO and other LCD splicing displays, etc., do not have mature LCD splicing displays suitable for outdoor display. 2 The display screen is planned to be used for outdoor display, but it is obviously found in the actual application that in the high temperature weather in summer, it cannot withstand the outdoor high temperature and the superposition of local power consumption causes the surface temperature rise of the LCD splicing screen to seriously exceed the temperature that the LCD splicing screen itself can withstand. When the range is raised, the screen is broken. Simultaneously (NC together) 2500cd / m 2 When th...

Problems solved by technology

[0006] 3) The brightness of special-purpose LCD panels can reach more than 1500cd / m2, but the cost and product stability will be reduced

[0019] After the above calculations, it can be concluded that the LCD screens of the three specifications can display normally at night and support high-definition display, but in an environment with sunlight during the day, none of the LCD screens can display normally outdoors (the screen can be seen during the daytime) 9.8cd / m at critical point 2 above)

[0021] For the same reason, some manufacturers (display screen manufacturers) have made a lot of efforts to make the LCD screen outdoors. 2 (cost considerations) increased to 1500cd / m 2 or higher, and then put it outdoors for display, and the result is that after the screen is refitted, the power generated by the screen itself increases significantly, and in addition to direct sunlight under strong sunlight in summer, the two temperatures add up, and the internal temperature rise of the screen continues to increase. The temperature greatly exceeds the temperature that the screen surface can withstand, causing the screen to break. At the same time, in order to make the display area larger, the splicing method cannot solve the impact of the natural environment such as rainproof, high and low temperature resistance at the splicing place. They are under the existing conditions. Display screen manufacturers only modify the brightness of the screen, and do not consider other conveniences. As a result, when the display screen is placed outdoors, after the screen status changes, the original LCD screen manufacturer cannot provide warranty for damage. The way of admitting bad luck seriously affects the loss of confidence in such products

This market is very huge, but except for this scheme, other schemes cannot be promoted on a large scale at present
