At the same time, the poster fixing part 3 on the top of the light homogenizing sheet can slide to the bottom of the guide rail 2. After the poster is installed on the poster fixing part 3 on the top of the light homogenizing sheet, the light homogenizing sheet is pushed upward so that the poster fixing part 3 on the top of the light homogenizing sheet can clamp the poster and slide along the guide rail 2 to the top of the guide rail 2. Thereafter, the fixing part 6 and the positioning part 5 are fixed and locked, so that the light homogenizing component 1 can be stationary, thus completing the efficient installation of the poster; when it is necessary to remove the poster from the light box frame 7, the fixing part 6 is removed to unlock the fixing part 6 and the positioning part 5, and the light homogenizing sheet is pulled downward, and then the poster on the poster fixing part 3 can be removed. Whether installing or removing the poster, it can be ensured that the sliding members 4 on the left and right sides of the light-homogenizing component 1 always maintain sliding contact with the guide rail 2 and the sliding members 4 will not slide out of the guide rail 2 .
