[0038] figure 1 It is a schematic cross-sectional view of the liquid crystal display panel of this embodiment after applying a bias voltage, figure 2 It is a three-dimensional exploded schematic view of the liquid crystal display panel of this embodiment before applying a bias voltage.

[0039] Please also refer to figure 1 and figure 2 , the liquid crystal display panel of the present embodiment comprises: a first substrate 11 is provided with a first electrode layer 12, and the first electrode layer 12 has a first surface 121; a second substrate 15, opposite to the first substrate 11 arranged in parallel, the second substrate 15 is provided with a second electrode layer 14, the second electrode layer 14 has a second surface 141, and the second surface 141 is corresponding to the first surface 121 of the first electrode layer 12; The blue phase liquid crystal layer 13 includes a blue phase liquid crystal, and the blue phase liquid crystal layer 13 is arranged between the...

Embodiment 2

[0045] image 3 It is a schematic perspective view of the liquid crystal display panel of this embodiment before applying a bias voltage. Such as image 3 As shown, the structure and driving method of the liquid crystal display panel of the present embodiment are the same as Embodiment 1, except that a microlens array 17 is also provided below the second electrode layer 14 and relative to the first electrode layer 12; thus it can help Focusing of light passing through the blue phase liquid crystal layer 13 . In other embodiments, the microlens array can also be disposed between the second electrode layer 14 and the second substrate 15 , depending on design requirements.

Embodiment 3

[0047] Figure 4 It is a schematic cross-sectional view of the liquid crystal display panel of the present embodiment after a bias voltage is applied. Such as Figure 4 As shown, the structure and driving method of the liquid crystal display panel of this embodiment are the same as those of Embodiment 1, except that a dielectric layer 19 is also provided below the second electrode layer 14 and opposite to the first electrode layer 12 to help pass blue Focusing of the light rays of the phase liquid crystal layer 13. In addition, the liquid crystal display panel of this embodiment is not provided with the light-shielding area of ​​Embodiment 1, but focuses the light passing through the blue-phase liquid crystal layer 13 on the black matrix of the color filter 18, and the black matrix achieves the effect of absorbing light. effect.

Abstract

The invention relates to a liquid crystal display panel, a driving method of the liquid crystal display panel and a liquid crystal displayer with the liquid crystal display panel. The liquid crystal display panel comprises a first substrate provided with a first electrode layer, a second substrate provided with a second electrode layer, a blue-phase liquid crystal layer arranged between the first substrate and the second substrate and a shading zone arranged on the second substrate, wherein the first electrode layer and the second electrode layer are arranged oppositely and bias voltage is exerted between the first electrode layer and the second electrode layer so that refractive index graded distribution of the blue-phase liquid crystal layer can be generated, and therefore light sources penetrating through the blue-phase liquid crystal layer are focused on the shading zone.

Description

technical field [0001] The invention relates to a liquid crystal display panel, its driving method and a liquid crystal display including it, especially a liquid crystal display panel using a blue-phase liquid crystal layer as a refractive index gradient lens, its driving method and a liquid crystal display including it. Background technique [0002] A liquid crystal display is a flat and thin display device. Because of its thinness, it has replaced the traditional cathode ray tube display in recent years and has become one of the most popular display devices at present. [0003] Wherein, the liquid crystal display mainly includes a liquid crystal display panel and a backlight module, and the backlight module is mainly arranged under the liquid crystal display panel, that is, on the side of the thin film transistor substrate, so as to provide a light source to the liquid crystal display panel. By controlling the display of pixels, images can be presented on the liquid crysta...
