Embodiment approach

[0041] In the present invention, there is no special limitation on the material of the magnetostrictive column, as long as it can be stretched under the action of a magnetic field. As a preferred embodiment of the present invention, the material of the magnetostrictive column includes any one of Ni-Co alloy, Ni-Co-Cr alloy, Ni-Co-Cu alloy, Ni-Zn-Co alloy or In any one of them, the first electrode and the second electrode are insulated and spaced apart from the magnetostrictive column.

[0042] exist figure 1 and figure 2 In the illustrated embodiment, the magnetostrictive column assembly 310 includes a first insulator 312 and a second insulator 314 . The first insulator 312 is arranged on the top of the magnetostrictive column 313, the second insulator 314 is arranged on the bottom of the magnetostrictive column 313, the first electrode 311 is arranged on the upper surface of the first insulator 312, and the second electrode 315 is disposed on the lower surface of the seco...

Abstract

The invention provides a liquid crystal display device. The liquid crystal display device comprises a liquid crystal panel, a backlight source and a front frame for connecting the backlight source with the liquid crystal panel. The front frame comprises transverse limiting parts and longitudinal limiting parts connected with the transverse limiting parts, wherein the longitudinal limiting parts are located on the outer side of the liquid crystal panel and surround the liquid crystal panel, the transverse limiting parts extend to the middle of the liquid crystal panel from the upper ends of the longitudinal limiting parts to be located above the light outlet face of the liquid crystal panel, the liquid crystal display device further comprises a gap adjusting mechanism, and the gap adjusting mechanism is used for adjusting gaps between the transverse limiting parts and the light outlet face of the liquid crystal panel. The gap adjusting mechanism can prevent light leakage when display in a dark state occurs and ensure that the liquid crystal panel can be firmly connected with the backlight source together in most states.

Description

technical field [0001] The invention relates to the field of liquid crystal display, and in particular relates to a liquid crystal display device. Background technique [0002] A liquid crystal display device includes a liquid crystal panel and a backlight. Since the liquid crystal panel and the backlight source are two independent components, it is inevitable that light leakage in the dark state will occur in the liquid crystal display device. In the prior art, the method of changing the liquid crystal material of the liquid crystal panel or changing the pixel circuit of the liquid crystal panel is usually used to improve the light leakage in the dark state of the liquid crystal display device. [0003] After the liquid crystal material or the pixel circuit of the liquid crystal panel is improved, the liquid crystal panel is turned on for a test to detect whether there is still light leakage in the dark state of the liquid crystal panel. [0004] However, sometimes even i...
