Liquid crystal module and display device thereof

Abstract

The invention discloses a liquid crystal module and a display device thereof. The liquid crystal module comprises: a backlight unit, and an upper polarizer, a first substrate, a color filter, a firstliquid crystal layer, a second substrate, a polarizing functional layer, a second liquid crystal layer, a third substrate and a lower polarizer that are located on one side of a light-emitting surfaceof the backlight unit and are superimposed in order, a frame glue and an isolation pad structure that are arranged between the first substrate and the third substrate, and a through hole running through the second substrate and the polarizing functional layer. The lower polarizer is close to the backlight unit, the frame glue is located on the periphery of the second substrate, and the isolationpad structure penetrates through the through hole to fix the second substrate relative to the first substrate and the third substrate. The number of the substrates and the number of the polarizers arereduced, and the gluing frequency in the production process is reduced; and the frame glue is only used at the peripheries between the first substrate and the third substrate for bonding, and the interiors of the first substrate and the third substrate are supported by the isolation pad structures in a jacking manner without comprehensive gluing.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal module and a display device thereof. Background technique [0002] Liquid crystal display panels have the characteristics of rich colors, good reliability, mature technology and relatively low cost. They are currently the most widely used display panels. However, liquid crystal display panels also have defects such as low contrast and impure colors. For the problem of low contrast, the existing technology adopts a new structure liquid crystal module, that is, two layers of liquid crystal display panels are stacked, such as figure 1 As shown, the upper liquid crystal module A has the same structure as the traditional liquid crystal module, including the upper polarizer 101, the upper glass 102, the color filter 103, the liquid crystal layer 104, the lower glass 105 and the lower polarizer 106; the lower liquid crystal module B Including upper polar...

[0002] Liquid crystal display panels have the characteristics of rich colors, good reliability, mature technology and relatively low cost. They are currently the most widely used display panels. However, liquid crystal display panels also have defects such as low contrast and impure colors. For the problem of low contrast, the existing technology adopts a new structure liquid crystal module, that is, two layers of liquid crystal display panels are stacked, such as figure 1 As shown, the upper liquid crystal module A has the same structure as the traditional liquid crystal module, including the upper polarizer 101, the upper glass 102, the color filter 103, the liquid crystal layer 104, the lower glass 105 and the lower polarizer 106; the lower liquid crystal module B Including upper polarizer 111, upper glass 112, liquid crystal layer 113, lower glass 114 and lower polarizer 115; because two pieces of glass are arranged between the liquid crystal layer of liquid crystal module A and the liquid crystal layer of liquid crystal module B, to enhance For contrast, two polarizers need to be installed between two pieces of glass; and when liquid crystal module A and liquid crystal module B are combined, it is necessary to make liquid crystal module A and liquid crystal module B as close as possible. The contact surface with the LCD module B is fully coated with glue, and the liquid crystal module A and the LCD module B also need to be glued multiple times during the box forming process, and the process is complicated
