Description

A kind of outdoor LCD
Technical field
The present invention relates to a kind of LCD, particularly relate 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.
Summary of the invention
The objective of the invention is provides a kind of outdoor LCD to solve the problems referred to above in order to solve the existing defective that can not use out of doors of LCD.
To achieve these goals, technical scheme of the present invention 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.
Above-mentioned a kind of outdoor LCD is characterized in that, described backlight module comprises the natural light assembly and cools off light source assembly separately.
Above-mentioned a kind of outdoor LCD is characterized in that described natural light assembly comprises outdoor optical collector and light-conductive optic fibre; Described outdoor optical collector connects light-conductive optic fibre, and light-conductive optic fibre connects display module.
Above-mentioned a kind of outdoor LCD is characterized in that, described independent cooling light source assembly comprises photometer, light source and light-conductive optic fibre; Described photometer connects light source, and light source connects light-conductive optic fibre, and light-conductive optic fibre connects display module.
Above-mentioned a kind of outdoor LCD is characterized in that, described independent cooling light source assembly also comprises heating radiator, and described heating radiator is arranged on the light source.
The beneficial effect that the present invention has: the brightness of LCDs is brought up to more than the 1500cd/m2, satisfy the requirement of outdoor graphic presentation, and provide possibility for further increasing display brightness, make things convenient for the display screen heat radiation, reduced the heat radiation power consumption, can make whole display system heat radiation power consumption under 40 degree hot weather conditions utilize the sun light lighting resource less than 200 watts, reduce system energy consumption, the energy consumption that can make whole giant-screen multimedia messages display system is at this below 500 watts.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Further understand and understanding for making architectural feature of the present invention and the effect reached had, cooperate detailed explanation, be described as follows in order to preferred embodiment and accompanying drawing:
Referring to Fig. 1, a kind of outdoor LCD, comprise the display module 100 that is used for the demonstration effect and be used for providing backlight module 200 backlight to display module 100, backlight module 200 connects display module 100, separate setting between display module 100 and the backlight module 200, make the increase of the luminotron quantity in the backlight module 200 not be subjected to the restriction in display module 100 spaces, for the intensity that further improves light source provides possibility, spatially isolated simultaneously contacting of display screen 110 in heater element and the display module 100 in the backlight module 200, improved the radiating effect of display screen 110, the possibility of having avoided outdoor display screen 110 to descend because of temperature rising display performance.
Display module 100 comprises display screen 110 and light guide plate 120, light guide plate 120 is arranged at the back side of display screen 110, the light source that backlight module 200 sends imports on the display screen 110 by light guide plate 120, the effect of light guide plate 120 is that the pointolite that passes over by light-conductive optic fibre is converted into area source, and being applicable to display screen 110 provides backlight.
Backlight module 200 comprises the natural light assembly 210 that utilizes natural light to supply light and utilizes artificial light source to supply the independent cooling light source assembly 220 of light, that is to say that backlight module 200 both can use outdoor natural light that light source is provided, and also can utilize artificial light source to supply light.
Natural light assembly 210 comprises the light-conductive optic fibre 212 that is used to gather the outdoor optical collector 211 of outdoor light and is used for conducting light; Outdoor optical collector 211 connects light-conductive optic fibre 212, light-conductive optic fibre 212 connects display module 100, outdoor optical collector 211 passes through the light that collects the transmission of light-conductive optic fibre 212, light is delivered in the light guide plate 120 in the display module 100, light guide plate 120 by display module 100 is converted into area source with the pointolite that light-conductive optic fibre 212 passes over again, provides backlight for display screen 110.The advantage of natural light assembly 210 is, because it is that the natural light of the open air of adopting is for light, so the part of sunshine as display backlight, the brightness that had both improved display screen makes again that brightness backlight is autosynchronous follows the variation of environmental light intensity and change.。
Cooling light source assembly 220 comprises the photometer 221 that is used to detect surrounding environment brightness, the light-conductive optic fibre 223 that is used to provide the light source 222 of light source and is used for conducting light separately; Photometer 221 connects light source 222, light source 222 connects light-conductive optic fibre 223, light-conductive optic fibre 223 connects display module 100, photometer 221 is controlled the luminous brightness of light source 222 by the brightness that detects surrounding environment, the light that light source 222 sends is by the transmission of light-conductive optic fibre 223, light is delivered in the light guide plate 120 in the display module 100, and the light guide plate 120 by display module 100 is converted into area source with the pointolite that light-conductive optic fibre 223 passes over again, provides backlight for display screen 110.Adopting separately, cooling light source assembly 220 supplies the advantage of light to be: utilize photometer 221 to make system can real-time monitor the variation of environmental light intensity, judge current belong to fine day, cloudy day, morning, noon or night, intensity by different ambient conditions is regulated light source makes display screen 110 be in the optimal display result state all the time.
