Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail。Following instance is used for illustrating the present invention, but is not limited to the scope of the present invention。
In describing the invention, it is necessary to explanation, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, for instance, it is possible to it is fixing connection, it is also possible to be removably connect, or connect integratedly；Can be mechanically connected, it is also possible to be electrical connection；Can be joined directly together, it is also possible to be indirectly connected to by intermediary, it is possible to be the connection of two element internals。For the ordinary skill in the art, it is possible to concrete condition understands above-mentioned term concrete meaning in the present invention。
Embodiment 1
As it is shown in figure 1, the display floater of the embodiment of the present invention, comprising: color membrane substrates 1 and primary diaphragm 2。Color membrane substrates 1 is provided with black streaking 11, and black streaking 11 crosses transparent area 12。Black streaking 11 is multiple, and multiple black streakings 11 arrange according to set mode and cross multiple transparent area 12, and transparent area 12 is for through three kinds of light of red, green, blue or red, green, blue, Bai Si kind light。Primary diaphragm 2 is located at the front of the exiting surface of color membrane substrates 1。Primary diaphragm 2 is provided with the first cylindrical lens 21, parallels with the edge of black streaking 11 in the axle center of the first cylindrical lens 21, and both the bearing of trend of the first cylindrical lens 21 was paralleled with the edge of black streaking 11。The projection on color membrane substrates 1 of first cylindrical lens 21 is at least partially disposed at transparent area 12, it is refracted to the front of black streaking 11 by the first cylindrical lens 21 from the light portion of transparent area 12 outgoing of color membrane substrates 1 with realization, from the light of backlight module outgoing by color membrane substrates 1 time, a part is blocked by black streaking 11, another part is from transparent area 12 outgoing, the light of outgoing directly penetrates in part through primary diaphragm 2, and some light penetrates from the front of black streaking 11 after being reflected by the first cylindrical lens 21。
It should be noted that, display floater also includes the structures such as backlight module, array base palte, circuit board, this is easy to understand for those skilled in the art, in description of the invention process, simple in order to what describe, omitted in description process, can not it is taken as that or need not there is this structure。
As shown in Figure 2, during display floater display, the parallel rays that backlight module sends is from color membrane substrates 1 outgoing, some light enters the first cylindrical lens 21, outgoing after the first cylindrical lens 21 reflects, and light is displaced to black streaking 11 front from going out transparent area 12, user before display floater is it is seen that whole panel goes out light, being absent from black streaking not territory, output optical zone, thus realizing the blanking purpose of black streaking, alleviating the screen door effect of display floater。
As shown in Figure 1, this display floater also includes secondary diaphragm 3, secondary diaphragm 3 is located at the exiting surface front of primary diaphragm 2, secondary diaphragm 3 is provided with the second cylindrical lens 31, paralleling with the edge of black streaking 11 in the axle center of the second cylindrical lens 31, the projection on color membrane substrates 1 of second cylindrical lens 31 is at least partially disposed at black streaking 11。That is, the front of the exiting surface of color membrane substrates 1 is located at primary diaphragm 2 and secondary diaphragm 3 interval successively。Owing to light is by, after the refraction of the first cylindrical lens 31, scattering occurring, the exit direction of light there occurs change, the exit direction of light is adjusted by the second cylindrical lens being located on secondary diaphragm 3, avoid light rays encounter interference so that whole display floater shows that uniformly blanking is effective。
Preferably, primary diaphragm 2 and secondary diaphragm 3 are made up of glass or resin material。In the present embodiment, the first cylindrical lens 21 is cylindricality biconvex lens, and the second cylindrical lens 31 is cylindricality biconvex lens。
Preferably, the distance between the first cylindrical lens 21 and the second cylindrical lens 31 is equal to the focal length sum of the first cylindrical lens 21 and the second cylindrical lens 31。Make to parallel from the light of the second cylindrical lens 31 outgoing and the extended line of the light from color membrane substrates 1 outgoing。Parallel from the light of the second cylindrical lens 31 outgoing with the light from color membrane substrates 1 outgoing, it is to avoid from the light rays encounter interference of the second cylindrical lens 31 outgoing, it is achieved good display effect。
Further, the radius of curvature of the first cylindrical lens 21 is less than the radius of curvature of the second cylindrical lens 31。Preferably, the radius of curvature of the first cylindrical lens 21 is 1/3～2/3 with the ratio of the radius of curvature of the second cylindrical lens 31, it is preferred that the ratio of the radius of curvature of the first cylindrical lens 21 and the second cylindricality radius of curvature is 1/2。The radius of curvature of the second cylindrical lens 31 is more than the radius of curvature of the first cylindrical lens 21, so that light generation scattering, the width of light becomes big, thus playing blanking effect better。
In order to avoid the second cylindrical lens 31 makes other light that need not reflect reflect, when second cylindrical lens 31 projection section on color membrane substrates 1 is positioned at transparent area 12, the part of transparent area 12 that the part that the projection of this part covers covers less than the projection on color membrane substrates 1 of first cylindrical lens 21。
Preferably, the width of the second cylindrical lens 31 is less than the width of black streaking 11。The Breadth Maximum of general black streaking is 5um。The width of the first cylindrical lens 21 is more little, blanking effect is more good, but the first cylindrical lens 21 is more little, the light passed through is more few, and light transmission capacity is not enough, also influences whether blanking effect, therefore, the width of the first cylindrical lens 21 can carry out adapt according to light intensity, and accordingly, the width of the second cylindrical lens 31 is also correspondingly adjusted。
