Description
The utility model relates to a kind of cover structure backlight, refers in particular to a kind ofly to be arranged at the back lighting device of cover backlight and the structure between the display panels by heat shield.LCD (Liquid Crystal Display, LCD) device product has low power consumption, economizes the energy, advantages such as portable, high-resolution, continuous pictures manifest though price is comparatively expensive at present, substitute traditional iconoscope monitor gradually in the monitor market.Be multiple in the demand market of notebook computer and both desktop monitors and grow up, in addition, Vehicular navigation demonstration, wall hung television, HDTV all kinds of electronics and IT products such as (high-definition televisions) are also constantly to be developed to using in military special requirement.
Known LCD device mainly comprises closure assembly display panels backlight.Closure assembly wherein backlight comprises a base, a reflector plate device, an earthing device, a pole plate device, a lamp tube device, a diffusion exhibition tabula rasa etc.Wherein this diffusing light guiding plate is to be locked on this base.
The LCD device will be because in the pattern of its liquid crystal display, very responsive to its peripheral temperature, too high peripheral temperature will make the transmittance of LCD panel reduce, and influence its usefulness and serviceable life.LCD need rely on back lighting device provides light source to show, under the restriction of LCD thickness, the heat energy that back lighting device sends is one of main cause that makes the rising of display panels peripheral temperature.
Yet in the design of LCD, at the peripheral temperature control of display panels, extremely limited protection design is only arranged at present, this demands urgently improving.
The purpose of this utility model is to propose a kind of cover structure of being made up of heat shield, cover backlight and fan backlight, it has can reduce the environment temperature of display panels when work, improve the function and the life-span of display panels, thereby solved the existing in prior technology problem.
The technical scheme that the utility model adopted is that it is arranged at by a heat shield between the back lighting device and a display panels of this cover backlight, can be transmitted to this display panels in order to reduce the heat production of back lighting device institute.
Cover structure backlight of the present utility model further provides on the chassis side that a plurality of air holes are arranged at this cover backlight, produce heat energy dissipation in order to the back lighting device of assisting this cover backlight, and several fans are locked on the base end face of this cover backlight, can dissipation in order to the back lighting device institute heat production of assisting this cover backlight.
Advantage of the present utility model is that it can reduce the environment temperature of display panels when work, and the function and the life-span of improving display panels whereby.
