Description
Technical field
The utility model relates to a kind of LCD, particularly relates to a kind of LCD that can use out of doors.
Background technology
Along with the present information development of science and technology, people the giant-screen multimedia messages is shown and the demand of human-computer interaction strong day by day, owing to LCD (LCD) had light, low-power consumption, bright in luster, advantages such as pixel exquisiteness, it has become the display screen of multimedia human-computer interaction first-selection.But at present LCDs also only limits the use of in indoor, can not be used for the open air, and its main cause is the first, backlight intensity too a little less than, human eye can't be seen the displaying contents of LCD clearly under strong outdoor solar light irradiation; The second, LCDs is subjected to the influence of environment temperature easily, and normal working temperature only is 50 degree.The scheme backlight of LCD has two kinds at present, and a kind of is that liquid crystal panel is placed cold cathode luminotron (CCF) behind, and the CCF luminotron can send certain heat, is unfavorable for the heat radiation of outdoor liquid crystal display, and the CCF luminous intensity has certain limitation.Second kind is to place light guide plate, and places light emitting diode (LED) in the side of light guide plate, and the brightness ratio CCF pipe of LED is big, but LED can only be placed on the limit, side of display, and placement space is limited.These two kinds of methods all are subjected to the restriction of its light source position space and entire display screen heat radiation, can't reach enough strong brightness it is used out of doors, thereby limit LCD use out of doors.The scheme that this patent proposes has overcome the shortcoming of above scheme backlight, and the brightness that has improved outdoor LCD makes display also can keep best display effect out of doors.
The utility model content
The purpose of this utility model is in order to solve the existing defective that can not use out of doors of LCD, to provide a kind of outdoor LCD to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of outdoor LCD comprises display module and backlight module, and backlight module connects display module, it is characterized in that, separates setting between described display module and the backlight module.
Above-mentioned a kind of outdoor LCD is characterized in that described display module comprises display screen and light guide plate, and described light guide plate is arranged at the back side of display screen.
