8. A display method for operating a display device for big data analysis according to any one of claims 1 to 7, comprising the steps of:

s1: the positioning control on the fixed block (3) is released by unscrewing the connection between the screw cap (42) and the threaded rod (41), the curtain (7) can be vertically placed towards the telescopic rod (2) after the folding mechanism (5) is folded, the vertical occupied space is reduced, and meanwhile, the position change on the angle of the curtain can be judged by the scale (47), so that the accurate angle adjustment and positioning are realized;

s2: the two groups of first connecting rods (53) and the second sleeves (54) are rotated downwards through the motor (45) and are close to the lower side of the first cross piece (51), meanwhile, the two groups of first connecting rods (53) downwards enable the two groups of second connecting rods (57) to move upwards, the thirty-first key (59) is moved to be close to the position of the first cross piece (51), folding collection of the curtain (7) is achieved, and automatic opening and closing are achieved through cooperation with control of the motor (45);

s3: when dismantling curtain (7) and installing, slightly powerful outwards dial or push round bar (68), fixture block (69), alright realize the dismouting to curtain (7), behind curtain (7) damaged or dirty, change easily clean, and when curtain (7) are not hard up, rotatory four sets of lead screws (66), round bar (68) just can take up curtain (7), reduce the unrestrained influence of wave to its production, the presentation of cooperation folding mechanism (5), when analyzing data in the projection, more stable.
