In the following description, for purposes of explanation and not limitation, specific details are set forth, such as methods, techniques for improving screen transmittance, in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known features are omitted so as not to obscure the description of the present invention with unnecessary detail.
In addition, in order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
As shown in fig. 1, the present invention provides a method for improving light transmittance of a screen, wherein the method comprises: a blind hole is formed in one surface, far away from the cover plate, of the screen to serve as a light-taking area when a front camera takes a picture; filling liquid crystal which is wrapped by a film and can move in the film in the blind hole; a force is applied to the film that moves the liquid crystal to the edge of the film.
Specifically, the film is a conductive film, and the cover plate is a glass cover plate.
The invention designs a scheme for improving the light transmittance of a screen, and realizes that a local area presents a better transparent state by displacing liquid crystal materials independently polymerized in a transparent conductive film area. As is known, the inside of the screen is filled with liquid crystal, and the transmittance of the liquid crystal is low, only about 60%. According to the invention, a blind hole is sunken on the surface of the screen, which is far away from the cover plate glass, and is used as a light-taking area when a front camera takes a picture, and liquid crystal wrapped by a conductive film is filled in the blind hole. The liquid crystal can complete the display of the whole screen together with the liquid crystal outside the conductive film.
As shown in fig. 2 to 4, in the screen according to the present invention, a blind hole 3 is opened on a surface of the screen 1 away from the cover plate 2, the blind hole 3 is filled with a liquid crystal wrapped by a film 4 and movable in the film 4, and a force applying member is provided in a circumferential direction of the film 4, the force applying member being configured to apply a force to the film 4 to move the liquid crystal to an edge of the film 4.
In one embodiment, the force applying member comprises: a coil 5 and a ring magnet 6, wherein the coil 5 is arranged on one surface of the film 4 far away from the screen 1, and the ring magnet 6 is arranged on the circumferential direction of the coil 5. That is, a coil 5 is provided on a surface of the film 4 remote from the screen 1, and a ring magnet 6 is provided in a circumferential direction of the coil 5.
As shown in fig. 5, in order to allow the liquid crystal to flow in the conductive film, it is necessary to use an energizing coil attached to the conductive film and a ring magnet around the coil. According to the right-handed screw rule principle, the electrified coil can generate a magnetic field. In the present invention, the current supplied to the coil 5 is direct current, and therefore the direction of the N pole generated by the coil is fixed. For example, in fig. 3, the N pole generated by the coil is directed toward the screen, the S pole is directed away from the screen, and the side of the ring magnet close to the coil is the S pole, so that a repulsive force is generated to the contacted energized coil. Due to the fixation of the conductive film and the energized coil, the same force as the coil is applied. The conductive film is deformed toward the direction of the force (i.e., the rightward direction in fig. 5) after being stressed, so that the liquid crystal in the center can be pressed to the edge. After the liquid crystal in the center of the conductive film is reduced, the light transmittance of the front camera below the area can be improved.
Alternatively, the current supplied to the coil may also be an alternating current. The acquisition of the alternating current is controlled by the mainboard. Due to the action of high-frequency alternating current, the electrified coil can repeatedly receive the attraction force and the repulsion force of the magnet, so that high-frequency vibration is generated. The conductive film is fixed to the energized coil so that the conductive film also vibrates at the same frequency. The vibration at the center of the conductive film pushes the liquid crystal inside the film away all around and diffuses outwards from the center of the circle. Since the liquid crystal is pushed to the edge by the shock wave caused by the vibration, the light transmittance of the under-screen camera is increased.
The invention also proposes a device comprising a screen as described in the above specific embodiments. Preferably, the center of the front camera of the apparatus coincides with the center of the film, wherein the position of the front camera is shown as position a in fig. 2, but of course, the front camera may be disposed at other positions, and is not limited specifically herein.
The invention provides a scheme for improving the light transmittance of a screen, which can realize that the screen in a local area presents a better transparent state and is beneficial to light transmission. Through the luminousness that improves the screen, set up preceding camera under the screen, realize comprehensive screen cell-phone.
The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present invention, and are intended to be included within the scope of the present invention.
