Abstract

The utility model belongs to the technical field of the screen design of the display, which is characterized in that the screen surface is a part of the inner face of the sphere defined by using an optimum visual distance between a user and the screen center as radius. The utility model complies with human ergonomics, and reduces difference of distances between the user eyes and each position of the screen to the minimum, so as to minimize requirement of eye zooming and reduce eye fatigue, which can dramatically improve eyesight of people.

Description

Ergonomics Internal Spherical Surface type screen

The utility model belongs to the screen design field of display, particularly a kind of screen construction that meets the display of ergonomics.

Common people think that eyes see that the thing on plane is best, also be the clearest, actually this is not so, only see with two wide during with interior plane body, it is right to be only, because when working as the plane seen greater than two width, the distance of eyes and planar central is different with the distance on both sides, thus when eyes from the Far Left to the center, again from the center during to rightmost, just the adjustment focal length that need always not stop causes the discomfort of user's eyes to reach the fatigue of further bringing body and mind easily.

The purpose of this utility model is for overcoming the weak point of prior art, designing a kind of Internal Spherical Surface type screen that meets ergonomics; It is that position and the optimum distance between screen center according to two of general users is radius, and the sphere that is marked is the screen of display device of the best curve radian of screen surface, makes it can reach the effect of the best of binocular vision.

A kind of ergonomics Internal Spherical Surface type screen that the utility model proposes is characterized in that, is radius with the distance of the optimum visual between user and screen center, and the part of the spherical inner face that is marked is a screen surface.

User described in the utility model is relevant with the size of screen size with the optimum visual distance between screen center, increases with screen size, and the optimum visual distance is bigger, and the curve radian of screen surface is littler.

The utility model minimizes user's eyes and the range difference between each position of screen, and it is minimum that the demand of eyes zoom is reduced to, and reduces the fatigue of eyes, and masses' eyesight is had great improvement effect.

The utility model can be used for the mechanical, electrical screen of various displays such as looking of relevant calculation.

Fig. 1 is an example structure synoptic diagram of the present utility model.

The example structure of the ergonomics Internal Spherical Surface type screen that the utility model is designed as shown in Figure 1, this screen 1 is the part with the Internal Spherical Surface of certain curvature radius, its four frame 2 can be identical with traditional flat screen, the embodiment of the radius-of-curvature of various sizes screen surface is: 15 cun individuals use the optimum visual distance of screen to be 50cm, the best arc-shaped curved surface of those 15 cun screens is exactly, and is the part of the Internal Spherical Surface that radius drew with 50cm; The optimum visual distance of 17 cun screens is 70cm, and the best arc-shaped curved surface of those 17 cun shieldings is exactly, and is the part of the Internal Spherical Surface that radius drew with 70cm; The optimum visual distance of 19 cun shieldings is 90cm, and the best arc-shaped curved surface of those 19 cun shieldings is exactly, and is the part of the Internal Spherical Surface that radius drew with 90cm ... the rest may be inferred; People more than 49 cun uses the optimum visual distance of shielding to be 300cm in this way, the best arc-shaped curved surface of those 49 cun shieldings is exactly, with a plurality of default best viewing location is the center, and (can set two rows for) is the part of the Internal Spherical Surface that radius drew with 300cm ... the rest may be inferred; The bigger public shows the radius-of-curvature of screen, and comprehensively each spectators's distance, position are converted definite.
