A kind of flexible display device of solid of dynamic displaying pictures
Technical field
The present invention relates to 3 d display device, especially a kind of three-dimensional flexible display device.
Background technology
Along with the lifting of science and technology and esthetic sentiment, the requirement of the visual effect that people bring for screen also improves day by day, in life common screen nearly 5,6 kind, widespread commercial mostly, be applied to the displaying of market advertisement, but still can not give stereoscopic sensation, if there is a kind of novel display technique, pattern can be presented in to people at the moment with three-dimensional form, will bring brand-new visual experience to people.
Screen display technology is in order to cater to the pursuit of people to visual experience and to grow up.Screen display is passed on various information for people intuitively and easily, has great development space.But planar coloured display screen, easily causes people's visual fatigue, can't be concerned about very much for the content of display screen.Cause the concerned degree of display screen significantly to reduce, do not reach the function of its expection.Existing stereo display often coordinates by light and stage property is assisted, utilize the visual illusion of people to form a kind of 3D effect, can not be at last 3 dimensions truly three-dimensional, existing three-dimensional light sensation imaging technique is also because technical costs is higher so that can not be widely used.
Dynamic 3 d display device, can bring new stereoscopic vision experiences, also bring different advertisement mode of communication to businessman simultaneously, people can experience its stereovision from different perspectives, both reached beholder for aesthetic high request, also cater to businessman and attracted eyeball, shown the object of its product.Aspect home decoration, 3 d display device technology can off the beaten track unalterable wall, and kinsfolk can be rich in relief Background by designed, designed, has different new impression every day.
In sum, the flexible display device of a kind of solid of dynamic displaying pictures has great development space in Attraction Degree, aspect interactive.Therefore, our living needs is this is rich in stereoscopic sensation, dynamically and the existence of new device that can human-computer interaction.
Summary of the invention
In order to overcome the deficiency that cost is higher, stereoeffect is poor, human-computer interaction is poor of existing stereo display mode, the invention provides the flexible display device of solid of the dynamic displaying pictures that a kind of cost is lower, stereoeffect good, human-computer interaction is good.

The present embodiment, to form a rounded convex as example, shields as example, with reference to Fig. 1 taking expansion link number as 10 × 10 principle.The present invention is a kind of by the build-in attribute of picture---gray-scale value, by driven by motor expansion link extension and contraction control, thereby forms expansion link height difference, represents the display device technology of stereoeffect.As Fig. 1, three-dimensional flexible display device is made up of external extension bar 4, interior expansion link 2, external extension bar retainer 6, interior expansion link position-limited rack 3, frame 5, guide rail 1, motor 8, computer control 9, described external extension bar retainer has the square hole of equidistant arrangement, described computer control 9 is controlled described motor 8 and on described guide rail 1, is laterally moved in every row below expansion link 2, drives expansion link to be retractable to relevant position.Interior expansion link 2 is arranged on interior expansion link position-limited rack 3, in restriction, expansion link 2 moves axially, external extension bar 4 (square) is arranged on external extension bar retainer 6, on external extension bar retainer 6 with the square hole of proper alignment, the spin motion of restriction external extension bar 4, frame 5 is assembled into one each several part.
The step of three-dimensional flexible display device dynamic displaying pictures is 1) picture segmentation is become to the total region equating with expansion link quantity, 2) described picture is converted to gray-scale map, and calculate the gray average in each region, 3) described area grayscale value is transformed to the controlled quentity controlled variable of controlling motor corner by equal proportion, 4) computing machine rotates to an angle according to described controlled quentity controlled variable control motor 8, and drives expansion link to be retractable to relevant position by screw rod.Specific embodiments is: the region that computer control unit 9 becomes sum to equate with expansion link quantity rounded convex picture segmentation, rounded convex picture is converted to gray-scale map, and the gray average that calculates each region is M (0-255), area grayscale value M equal proportion is converted into the controlled quentity controlled variable N that controls motor, controls motor 8 anglec of rotation S according to controlled quentity controlled variable N.Motor 8 moves to below the shaft coupling 7 of interior expansion link 2 on guide rail 1, and rotate respective angles S1, because interior expansion link 2 is limited respectively with external extension bar 4, external extension bar 4 will be retractable to corresponding height H1, arrive after specified altitude assignment, motor 8 moves in next row below expansion link 2 shaft couplings 7 on guide rail 1, rotation respective angles S2, and lifting expansion link is to corresponding height H2.Expansion link 2 belows in motor 8 moves to last row, and rotate after respective angles S, display device demonstrates three-dimensional rounded convex.When motor reverse rotation, expansion link will be got back to initial position, return to plane.Under the control of computing machine, choose fast-changing picture, change the output time of rotation controlled quentity controlled variable, the dynamic solid that can realize picture shows.
Adopt image pixel gray-scale value control expansion link proposed by the invention to form the method for 3 d display device, by computing machine, picture is simply processed, control the displaying contents of display device, realize stereoeffect, can replace the painting advertisement wall of each megastore, can apply to displaying and the advertisement in the places such as buildings, square, market, and the decoration of household internal etc., separately also can be applicable to the displaying of three-dimensional fountain according to picture gray scale, under the contour prerequisite of water column, control the lifting of water jet, form three-dimensional water column face.
