Abstract
The invention provides a display device for projection. The device comprises a light source, a display screen, and a reflecting cup, wherein the light source is under the reflecting cup, and the display screen is above the reflecting cup. The display device has the advantages that the display device for projection has a small size, the use of the display device in a portable product is facilitated, a brightness image display effect can be obtained, and the display device can work in a high temperature environment.
Description
Technical field
The present invention relates to display device, more particularly to a kind of projection display device.
Background technology
The scheme used by the projector equipment of main flow is three kinds of DLP and 3LCD, laser in the market, wherein first two mode is all used to bulb as light source, and such light source all can only be enough reluctantly at last to the purity of picture brightness and color, while the life-span of bulb is obvious short slab.
Laser projection device can overcome both the above projection pattern defect, and long working life, light-source brightness is reduced with the decay of time, so as to because of prolonged work screen intensity will not be caused dimmed；Colour gamut extensively can be good again reproducing color therewith, it is ensured that color purity and saturation degree.
But, several main flow projection arrangements of the above have the following disadvantages：
1. volume is excessive, is unfavorable for being used on portable product；
2. generate heat excessive, it is impossible to used in 70 DEG C of high temperature above environment.
The content of the invention
In order to solve the problems of the prior art, the invention provides a kind of projection display device.
The invention provides a kind of projection display device, including light source, display screen and reflector, the light source is located at reflector lower section, and the display location is in reflector top.
As a further improvement on the present invention, projection display device also includes even smooth film, and the even smooth film is located between the reflector and the display screen.
As a further improvement on the present invention, projection display device also includes brightness enhancement film, and the brightness enhancement film is located between the even smooth film and the display screen.
As a further improvement on the present invention, projection display device also includes heat-protecting glass, and the heat-protecting glass is located between the reflector and the even smooth film.
As a further improvement on the present invention, projection display device also includes support, and the even smooth film, the brightness enhancement film and the display screen are pressed on the bracket successively.
As a further improvement on the present invention, the heat-protecting glass is arranged on the reflector, and the reflector is arranged on support lower section.
As a further improvement on the present invention, the projection display device also includes the radiator fan for the heat that the light source is produced to be distributed.
As a further improvement on the present invention, the display screen is LCDs.
As a further improvement on the present invention, the reflector is to become perpendicular to or be approximately perpendicular to the reflector of the display screen surface light by the light that the light source sends.
As a further improvement on the present invention, the light source is LED point light source or LED area light source.
The beneficial effects of the invention are as follows：Projection display device small volume of the invention, used beneficial on portable product, and can worked in high temperature environments again.
Brief description of the drawings

Fig. 2 is the light schematic diagram that light source of the invention sends.
Fig. 3 is the light schematic diagram that light source sends after light source of the invention installs reflector.
Specific embodiment
As shown in Figures 1 to 3, the invention discloses a kind of projection display device, become perpendicular to or be approximately perpendicular to the reflector 2 of the surface light of the LCDs 7 including light source 1, LCDs 7 and by the light that the light source 1 sends, the light source 1 is located at the lower section of the reflector 2, and the LCDs 7 is located at the top of the reflector 2.
The light that light source 1 sends is become perpendicular to or is approximately perpendicular to the light on the surface of the LCDs 7 by reflector of the invention 2, lifts the service efficiency of light, in the case where equal light intensity is produced, reduces the heating of light source 1, reduces the power of light source 1.
Projection display device also includes even smooth film 5, and the even smooth film 5 is located between the reflector 2 and the LCDs 7.It is more uniform during 7 surface of LCDs that even smooth film 5 is projeced into light.
Projection display device also includes brightness enhancement film 6, and the brightness enhancement film 6 is located between the even smooth film 5 and the LCDs 7.Brightness enhancement film 6 coordinates reflector 2 to use, efficiency of lifting effect of light when LCDs 7.
Projection display device also includes heat-protecting glass 3, and the heat-protecting glass 3 is located between the reflector 2 and the even smooth film 5.
Projection display device also includes support 4, and the even smooth film 5, the brightness enhancement film 6 and the LCDs 7 are pressed on the support 4 successively.
The heat-protecting glass 3 is arranged on the reflector 2, and the reflector 2 is arranged on the lower section of the support 4.
The projection display device also includes the radiator fan 8 for the heat that the light source 1 is produced to be distributed.
The light source 1 is LED point light source or LED area light source.
Projection display device small volume of the invention, used beneficial on portable product, and can worked in high temperature environments again, while good image quality can be produced under outdoor bright light environments.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert that specific implementation of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, should all be considered as belonging to protection scope of the present invention.
