Heat endurance inside display screen 10.Also, because the backboard 220 of glass material also has the characteristic of low thermal conductivity, Ke Yibao
Card backboard 220 maintains a less model in the temperature difference close to the side of thermal component 230 and the remote side of thermal component 230
In enclosing, and then avoid because backboard 220 is deposited close to the side of thermal component 230 and away from the deformation that the side of thermal component 230 occurs
Cause the problem of backboard 220 is deformed in larger difference, be effectively improved the reliability of LCDs 10 and display device
And security.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
