The embodiment of the invention discloses a spliced screen and a preparation method thereof. In one specific embodiment, the spliced screen comprises a plurality of display modules and a cover plate arranged on the plurality of display modules; each display module comprises a base, a supporting piece fixed to the base and a display panel arranged on the supporting piece, and the bases corresponding to the adjacent display modules are connected with each other; the display panel comprises a plane display area and a bonding area arranged on one side of the plane display area, and the bonding area is bent towards the side facing the light emitting side; and in one direction, the plurality of display modules comprise display modules of which the bonding areas are oppositely arranged, and the oppositely arranged bonding areas form a first spliced area. According to the spliced screen, the splicing seam effect of the spliced screen can be effectively weakened, the picture display effect of the spliced screen is optimized, and a user cannot see splicing traces in the visual effect.

The invention provides a spliced screen and a display device. The spliced screen is formed by splicing at least two sub screens. Every two adjacent sub screens are connected through connectors. Each connector comprises at least two connecting columns and clamping mechanism. At least one connecting column is arranged on each sub screen in every two adjacent sub screens, the clamping mechanisms are used for applying clamping force to the portions between the at least two connecting columns to make the at least two connecting columns clamped and fixed, and the at least two connecting columns are connected through the clamping mechanism. According to the spliced screen, the connectors are arranged between the every two adjacent sub screens, the every two adjacent sub screens are connected through the connectors to form the spliced screen, the clamping mechanisms in the connectors can be utilized to clamp and fix the connecting columns arranged on the sub screens, the every two adjacent sub screens can be connected together, and therefore gaps at the joints of the every two adjacent sub screens can be reduced, and the image display effect of the spliced screen is improved.

The application discloses a power generating circuit and a display device thereof. The power generation circuit outputs a first voltage and transmits it to a plurality of pixels of the display panel. The first voltage has a predetermined high voltage level. The power generation circuit includes a voltage output circuit and a voltage conversion circuit. The voltage output circuit outputs a second voltage , the voltage conversion circuit is electrically connected to the voltage output circuit, and outputs the first voltage according to the second voltage and a control signal; wherein, within one period of the first voltage, the control signal increases the first voltage output by the voltage conversion circuit to a predetermined high voltage level, and make the highest voltage level of the last falling edge of the first voltage less than the predetermined high voltage level. The application can effectively improve the capacitive coupling effect and make the display effect more excellent.

The invention provides a liquid crystal composition and a liquid crystal display device. The liquid crystal composition comprises a liquid crystal main body, a first monomer and an initiator. The first monomer is one selected from a monomer represented by formula 1, a monomer represented by formula 2 and a monomer represented by formula 3; and R1, R2, R3, R4, R5 and R6 are as described in the description.
