The present invention relates to a lenticular screen, and more particularly, to a zoom display integrated lenticular screen.

Background

With the continuous development of economy, high-tech products are gradually brought into daily life. In recent years, the research results on display are quite numerous, and various display methods are available today, and miniaturization and weight reduction of display devices are gradually being proposed as a new requirement while satisfying various functional requirements. The traditional display generally only has a display function and does not have an imaging function, and the whole structure is particularly heavy and not beneficial to the development requirement of light weight unless a display and imaging system superposition mode is adopted. Most of current high and new technology products such as various intelligent glasses, intelligent screens and the like do not adopt display imaging integration, so the volume of the product can be enlarged along with the product, the weight is obviously increased, and the wearing feeling and the using effect are also obviously reduced. Therefore, a novel display imaging integrated product is urgently needed to improve the quality of the product, and light weight and miniaturization are realized while the required functions are met, so that the portability and experience of the product are greatly improved.

Detailed Description

The following detailed description will provide an embodiment of a zoom display integrated lenticular screen according to the present invention, and further describe the present invention. It should be noted that the following examples are only for illustrative purposes and should not be construed as limiting the scope of the present invention, and that the skilled person in the art may make modifications and adaptations of the present invention without departing from the scope of the present invention.

The invention provides two embodiments by taking two different driving modes as examples. The first is driving based on an electrowetting driving method. As shown in the attached figure 1, when the filling medium I2 is silicone oil and the filling medium II4 is electrolyte liquid or ionic liquid, a liquid-liquid interface is formed between the two liquids. Corresponding instructions are sent to the liquid zoom lens driving module 7 through the general driving module 8, and the contact angle between the two liquids is changed by changing the voltage applied to the two ends of the liquid electrode, so that the curvature radius of a liquid-liquid interface is changed, the focal length of the liquid lens is finally changed, and zooming is realized; meanwhile, the main driving module 8 sends corresponding instructions to the transparent display driving module 6, so that real-time display is realized on the basis of zooming. As shown in fig. 2, which enables real-time display of the myopia correction status.

The second embodiment is based on a mechanical force actuation. As shown in fig. 1, when the medium II is air, the zooming principle is based on the deformation of the elastic membrane. When the liquid zoom lens driving module 7 outputs corresponding mechanical driving parameters, the elastic membrane generates a deformation corresponding to the mechanical driving parameters, and a membrane surface with a changed curvature is obtained, so that zooming is realized. When the membrane surface is convex by the driving force, the hyperopia compensation can be realized, and different convex degrees correspond to different compensation diopters. Meanwhile, the transparent display driving module 6 also realizes the real-time display function along with the output of the corresponding driving parameters, as shown in fig. 3.

Fig. 4 is a graph of the output driving parameters of the liquid zoom lens driving module 7 and the screen brightness of the integrated lens, and it can be seen that the diopter of the lens gradually increases with the increase of the voltage.

The transparent display in the zoom display integrated lens screen can be realized by using OLED, LCoS, Micro-LED and the like, the functions of compensating eyesight and realizing real-time display are realized, and AR change, glasses intellectualization, navigation, real-time translation, object recognition, distance judgment and the like in a depth scene can also be realized.
