Description

Technical Field

[0001] The present invention relates to a pattern display device, and particularly to a display device that superimposes static patterns and dynamic patterns. Background Art

[0002] Pattern display devices such as billboards, store fronts, bulletin boards, advertising light boxes, display racks, desktop display signs, desktop ornaments, display cabinet bodies with attached billboards, exterior billboards of vending vehicles, billboards attached to pedestrian and vehicle access control, background boards of store display cabinet hanging boards, bus stop billboards, elevator lobby billboards, murals, mounted paintings, night lights, etc. will display static patterns or dynamic patterns. Their current structural designs are divided into the following five categories: Category 1: A sheet material layer provided with a static pattern is arranged on a display board, and a protective transparent material layer can also be arranged on the outside. The static pattern reflects the ambient light on the outer side to play the role of displaying the pattern during the day; Category 2: A surface-emitting structure body is arranged inside the sheet material layer of the static pattern. The light of the surface-emitting structure body penetrates the sheet material layer to display the static pattern, playing the role of displaying the pattern at night; Category 3: Two electric reels are arranged at both ends of the sheet material layer of the static pattern. By winding the sheet material layer clockwise or counterclockwise through the electric reels, the sheet material layer is wound up on the electric reels to achieve the effect of switching static patterns; Category 4: An electronic display screen (such as liquid crystal, plasma, LED, etc.) is used to display static and / or dynamic patterns; Category 5: A raster painting is arranged inside a grating plate composed of arranged prisms, and the light refraction of the prisms is used to realize the transformation of the picture.

[0003] However, in practical applications, we have found the following defects: (1) For the pattern display devices of the first, second, and third categories, they can only display static patterns and cannot display dynamic patterns. Although the third category of display device makes the static pattern move, it only switches between different static patterns. Similar dynamic patterns are more attractive than static patterns. (2) Although the fourth category of pattern display device has many advantages such as being able to display dynamic patterns and being convenient for changing patterns, it still has defects such as high price, poor display effect under strong ambient light (such as in summer), the cold light source being relatively dazzling, and high power consumption. (3) The fifth category of pattern display device can realize the transformation of 2-4 patterns, but it has defects such as poor effective visual distance and pattern visual effect. Chinese Patent No. CN2020113502571 describes "a raster painting device capable of dynamically displaying multiple pictures based on a fixed viewing angle". By driving the support frame to move with a reciprocating movement mechanism, and then driving the drawing board to move left and right, multiple pictures can be continuously displayed, and an animation or video can be visually experienced to be repeatedly displayed on the picture. This invention has defects such as poor effective visual distance and pattern visual effect.

[0004] To address these deficiencies, we will make improvements in several aspects, such as being able to display dynamic patterns, having a low cost, having good display effects both in strong external environmental light and in dark external environmental light, not being dazzling, and having low power consumption. In the present invention, the outer side refers to the direction in which the display device faces the external environment; the inner side refers to the direction from the external environment towards the inside of the display device, which is the opposite direction of the outer side; the inner side surface refers to the surface of an object facing the geometric center point; the outer side surface refers to the surface of an object facing the external environment.
