Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.Should be understood that, embodiment described herein only, for description and interpretation the present invention, is not limited to the present invention.
The invention provides a kind of display device, as shown in Figure 2, this display device comprises display panel 1 and backlight, display panel 1 is provided with polaroid (not shown) towards the surface of backlight, described backlight comprises the optical diaphragm group with the adjacent setting of described polaroid, is provided with at least one septum pellucidum underbed 5 between described polaroid and optical diaphragm group 4.
As shown in Figure 1, backlight can also comprise reflector plate 2, light guide plate 3 and optical diaphragm group 4, and optical diaphragm group 4 arranges between display panel 1 and light guide plate 3, further improves the light that the exiting surface of light guide plate 3 sends.Optical diaphragm group 4 can comprise upper prismatic lens, diffuser plate and the lower prismatic lens between light guide plate 3 and display panel 1.
In the present invention, between polaroid and adjacent optical diaphragm group 4, be provided with septum pellucidum underbed 5, thereby be given a shock in display device (as, carry out vibration test) time, can prevent that polaroid from directly contacting with optical diaphragm group 4, thereby reduce the probability that mutual scuffing occurs for described polaroid and optical diaphragm group 4, improve the quality of products.
As a kind of embodiment of the present invention, septum pellucidum underbed 5 can be arranged on optical diaphragm group 4 on the surface of display panel 1 and/or be arranged on described polaroid on the surface of optical diaphragm group 4.When being provided with a plurality of septum pellucidum underbed 5 between described polaroid and optical diaphragm group 4, a plurality of septum pellucidum underbeds 5 can all be arranged on optical diaphragm group 4 on the surface of display panel 1; Also can all be arranged on described polaroid on the surface of optical diaphragm group 4; Partially transparent chock insulator matter 5 can also be arranged on optical diaphragm group 4 on the surface of display surface 1, another part septum pellucidum underbed 5 be arranged on polaroid on the surface of optical diaphragm group 4.
Be understandable that, described " surface towards display panel 1 of optical diaphragm group 4 " refer to, the surface towards display panel of the diaphragm of close display panel in optical diaphragm group 4.
To septum pellucidum underbed 5, the set-up mode on optical diaphragm group 4 and described polaroid is not construed as limiting in the present invention, for example, can adopt the mode of bonding mode, engaging etc., if can so that septum pellucidum underbed 5 be fixedly installed on optical diaphragm group 4 on the surface of display panel 1 and/or be arranged on described polaroid on the surface of optical diaphragm group 4.
Particularly, septum pellucidum underbed 5 can be arranged in optical diaphragm group 4 and/or be arranged on described polaroid by bonding mode, that is, septum pellucidum underbed 5 and optical diaphragm group 4 between the surface of display panel 1, be provided with jointing material; And/or septum pellucidum underbed 5 and described polaroid between the surface of optical diaphragm group 4, be provided with jointing material.
