Description

[Technical Field]

[0001] [CROSS-REFERENCE TO RELATED APPLICATIONS] This application is based on Chinese Patent Application No. 202310323226.4, entitled "Display Screen and Radian Adjustment Mechanism," filed on March 22, 2023, which is incorporated herein by reference in its entirety.

[0002] The present invention relates to the field of display screens, and more particularly to display screens and radian adjustment mechanisms. [Background technology]

[0003] Current curved screens generally use a radian adjustment mechanism behind the screen to adjust the radian of the curved screen. For example, in Chinese Patent Application No. 202022600971.3, entitled "Curved Joining Mechanism and Curved Display Screen," the radian of the display screen is changed by sliding the first and second joints relative to each other. Also, in Chinese Patent Application No. CN201810955925.X, entitled "Curved Adjusting Device and LED Display Screen," the radian of the display screen is changed by sliding the shell and intermediate plate relative to each other. The inventors discovered that while the designs in these two patents allow the radian of the display screen to be adjusted, the radian of the display screen after adjustment is not a perfect arc, resulting in a partial bend in the display screen, which may damage the LED chips in the bent portion.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understandable, specific embodiments of the present invention will be described in detail below with reference to the drawings. In order to facilitate a full understanding of the present invention, many specific details are set forth in the following description. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the scope of the present invention, so the present invention is not limited to the specific implementations disclosed below.

[0021] It should be noted that when an element is said to be "anchored" to another element, it may be directly attached to the other element or there may be a centrally located element. When an element is considered to be "connected" to another element, it may be directly attached to the other element or there may be a centrally located element.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. The terms used in the specification of the present invention are intended to describe specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0023] 3 and 4, the display screen includes a radian adjustment mechanism, which includes a first unit 1, a second unit 2, a first slider 3, and a second slider 4. The first slider 3 and the second slider 4 are fixedly connected to the first unit 1. The second unit 2 is provided with a first arc-shaped groove 6 and a second arc-shaped groove 7. The centers of the first arc-shaped groove 6 and the second arc-shaped groove 7 do not overlap. The first slider 3 is slidable in the first arc-shaped groove 6, and the second slider 4 is slidable in the second arc-shaped groove 7. The use of two arc-shaped grooves with different centers limits the sliding of the first unit 1 and the second unit 2, thereby solving the problem that the display screen does not have an ideal arc shape when adjusting the radian of the display screen when there is only one arc-shaped groove.

[0024] 5, in some embodiments, the method for determining the first arcuate groove 6 and the second arcuate groove 7 is as follows: a first point and a second point are taken in the second unit 2; When the display screen radian is 0 degrees, the first point is at position A9 and the second point is at position E12; If the display screen is in radians of X degrees, the first point is at position B10 and the second point is at position F13; When the display screen radian is −X degrees, the first point is at position C11 and the second point is at position G14; An arc line L18 formed by connecting the positions A9, B10, and C11 is on the same circle as the first arc-shaped groove 6, An arc line M19 formed by connecting the position E12, the position F13, and the position G14 is on the same circle as the second arc-shaped groove 7.

[0025] The arc line L18 is the ideal locus along which the first point changes from -X degrees to X degrees, and therefore the first arc-shaped groove 6 is on the same circle as the arc line L18, and therefore the first arc-shaped groove 6 is also the ideal locus along which the display screen changes from -X degrees to X degrees.

[0026] The arc line M19 is the ideal locus along which the second point changes from -X degrees to X degrees, and therefore the second arc-shaped groove 7 is on the same circle as the arc line M19, and therefore the second arc-shaped groove 7 is also the ideal locus along which the display screen changes from -X degrees to X degrees.

[0027] When adjusting the radian of the display screen, both the first arc-shaped groove 6 and the second arc-shaped groove 7 limit the deformation of the display screen, thereby avoiding bending of a part of the display screen when adjusting the radian of the display screen.

[0028] Referring to Figures 3 and 4, in some embodiments, a third slider 5 is further fixedly provided on the first unit 1, a third arc-shaped groove 8 is provided on the second unit 2, the third slider 5 is slidable within the third arc-shaped groove 8, and the centers of the first arc-shaped groove 6, the second arc-shaped groove 7, and the third arc-shaped groove 8 do not overlap.

[0029] 5, in some embodiments, the method for determining the third arcuate groove 8 is as follows: a third point is taken in the second unit 2; When the display screen radian is 0 degrees, the third point is at position H15; If the display screen radian is X degrees, the third point is at position I16; When the display screen radian is −X degrees, the third point is at position J17; An arc line N20 formed by connecting the positions H15, I16, and J17 is on the same circle as the third arc-shaped groove 8.

[0030] The arc line N20 is the ideal locus along which the third point changes from -X degrees to X degrees, and therefore the third arc-shaped groove 8 is on the same circle as the arc line N20, and therefore the third arc-shaped groove 8 is also the ideal locus along which the display screen changes from -X degrees to X degrees.

[0031] When adjusting the radian of the display screen, the first arc-shaped groove 6, the second arc-shaped groove 7 and the third arc-shaped groove 8 simultaneously restrict deformation of the display screen, and one surface is determined by three points, so that bending of part of the display screen is avoided when adjusting the radian of the display screen.
