angle block

4, 3 integrated designs of lower frame, solve the shortcoming of the single cross-section of aluminium alloy, can utilize 3 tip of lower frame to utilize angle block 4 specialization cooperation processing when adopting aluminium alloy lower frame 3, and realize lower frame 3 and center 1 through angle block 4 and realize the cooperation, make lower frame 3 and center 1 cross-section simplification, be convenient for process, with low costs, realize frameless display device 10's super thinization on the whole moreover.

Meanwhile, the frameless display device 10 is characterized in that the two ends of the middle frame 1 and the two ends of the lower frame 3 are hermetically connected by utilizing the corner blocks 4, the movement between the middle frame 1 and the lower frame 3 is limited by the corner blocks 4, the middle frame 1 and the lower frame 3 are prevented from being extruded on the display panel 2 installed between the middle frame 1 and the lower frame 3 when being installed and carried, the performance of the display panel circuit 22 is effectively guaranteed through the sealing connection of the corner blocks 4, the middle frame 1 and the lower frame 3, and the performance of the frameless display device 10 is further effectively guaranteed.

To sum up, the utility model discloses a frameless display device, the lower frame of locating the center opening part includes preceding deckle board, preceding deckle board pressure is held on the display panel that trailing flank and frame construction's leading flank are connected simultaneously, and have the clearance between preceding deckle board and the center, accept in the clearance through the boss with on the hornblock, and with preceding deckle board and center sealing connection, when display panel's below is provided with the circuit, can realize that the lower frame well cooperates with the center when carrying out good protection to the display panel circuit, and then effectively guarantee display panel's performance.

Furthermore, the above-described figures are merely schematic illustrations of processes included according to exemplary embodiments of the present invention, and are not intended to be limiting. Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein.
