Embodiment
The problem that exists in order to solve prior art, the embodiment of the present invention provides a kind of method for displaying image and terminal equipment of terminal equipment.This technical scheme adopts the rear-projection technology, makes terminal equipment that the function that LCD screen just can realize that image shows need be set, and has reduced the manufacturing adult of terminal equipment; When wanting to increase picture display face when long-pending, can realize by the propagation distance of region growing for image light beam, its extra cost is also cheaper.Further, this technical scheme also adopts shadow casting technique, makes terminal equipment realize projecting function, has further increased display area, has strengthened the function of terminal equipment, has satisfied client's multiple demand.
As shown in Figure 1, the embodiment of the present invention provides a kind of method for displaying image of terminal equipment, comprising:
S101, main frame output video data;
S102, micro projection system receiving video data are processed into image beam with video data;
S103, micro projection system form image with the lower surface perpendicular projection of image beam towards projection screen on projection screen, wherein, projection screen is positioned at the lower surface of the transparent front that connects main frame one end.
The structure of above-mentioned terminal equipment is as shown in Fig. 2 A-2B.
The lower surface of transparent front arranges projection screen, be similar to display screen on image, when micro projection system with image beam during towards the lower surface perpendicular projection of projection screen, according to the rear-projection principle, the user just can see image from the upper surface of projection screen, make from function and realized the function that image shows, compare the terminal equipment of existing employing LCD screen, it is made adult and decreases.When wanting to increase picture display face when long-pending, can realize by the propagation distance of region growing for image light beam, its extra cost is also cheaper.
Method shown in Figure 1 makes terminal equipment have common image display function, has projecting function concurrently in order to make terminal equipment, further increases display area, strengthen the function of terminal equipment, satisfy client's multiple demand, above-mentioned method for displaying image can also comprise the steps:
A1, main frame receive the mode instruction of input.
A2, when mode instruction is the projection mode instruction, micro projection system controlling projection screen moves to predeterminated position, makes image beam vertically pass transparent front; When mode instruction was the rear-projection mode instruction, micro projection system controlling projection screen moved to the lower surface of transparent front.
When projection screen moved to predeterminated position, image beam can see through transparent front, projected on the projection wall that is positioned at transparent front the place ahead or projection screen and formed image, made terminal equipment realize projecting function; When projection screen moved to the lower surface of transparent front, terminal equipment recovered common image display function.
Wherein, due to when the rear-projection pattern, the user watches from the upper surface of projection screen, image should be spent by flip horizontal 180, just can make the user see image in the right direction, therefore, when mode instruction was the rear-projection mode instruction, micro projection system also should be with image beam flip horizontal 180 degree.
As shown in Fig. 2 A-2B, a kind of terminal equipment that the embodiment of the present invention provides comprises main frame 21, is used for the output video data, also comprises:
Transparent front 22, an end of connection main frame 21;
Projection screen 23 is arranged at the lower surface of transparent front 22; Its material can adopt the two sides all can demonstrate the translucent material of projected image, as projection screen etc.;
Micro projection system 24 is used for receiving video data, and video data is processed into image beam, and with the lower surface perpendicular projection of image beam towards projection screen 23.
The lower surface of transparent front 22 arranges projection screen 23, be similar to display screen on image, when micro projection system 24 with image beam during towards the lower surface perpendicular projection of projection screen 23, according to the rear-projection principle, the user just can see image from the upper surface of projection screen 23, make from function and realized the function that image shows, compare the terminal equipment of existing employing LCD screen, it is made adult and decreases.When wanting to increase picture display face when long-pending, can realize by the propagation distance of region growing for image light beam, its extra cost is also cheaper.
Wherein, micro projection system 24 can be first micro projector, is used for receiving video data, and video data is processed into image beam, and with the lower surface perpendicular projection of image beam towards projection screen 23.The first micro projector can directly adopt existing suitable micro projector, and its operation principle no longer describes in detail.Be suitable for the less terminal equipment of the long-pending requirement of picture display face with the first micro projector as micro projection system 24.
For the thickness of attenuate terminal equipment, make the volume of terminal equipment less, make simultaneously picture display face long-pending larger, as shown in Figure 3, micro projection system 24 can comprise:
The second micro projector 241 is used for receiving video data, and video data is processed into image beam, and with the direction projection of image beam along the lower surface that is parallel to projection screen 23;
Speculum 242 be used for to change the direction of the image beam that the second micro projector 241 projects, and makes image beam towards the lower surface perpendicular projection of projection screen 23.
The length direction of the second micro projector 241 is parallel to the length direction of terminal equipment, makes the thickness of terminal equipment thinner; After the image beam that speculum 242 reflection the second micro projectors 241 project, make the propagation distance of image beam increase, thereby make the picture display face of terminal equipment long-pending larger.
Above several terminal equipment only has common image display function, in order to make this terminal equipment have projecting function concurrently, further increase display area, strengthen the function of terminal equipment, satisfy client's multiple demand, as shown in Fig. 4 A, the main frame 21 shown in Fig. 2 A-2B (or Fig. 3) may further include:
