The invention discloses an outdoor advertising display screen facilitating dust removal. The display screen comprises a supporting base, a lifting motor, a lead screw A, a lifting block, a display screen fixing frame, a display screen body, a driving motor, a lead screw B, a dust removal wiper and a rainproof device, the lifting motor is fixedly mounted in the supporting base, the lifting block is mounted on the lead screw A in a threaded manner, the display screen fixing frame is fixedly welded on the front side of the lifting block, the display screen body is mounted in the display screen fixing frame, the driving motor is mounted on the outer side of a right vertical plate, the dust removal wiper is fixedly mounted between a screw sleeve and a sliding sleeve, a supporting rod is welded on the upper side of a fixing support, and the rainproof device is mounted at the upper end of the supporting rod. According to the outdoor advertising display screen, the surface of the display screen can be automatically wiped, on one hand, time is saved, working efficiency is improved, on the other hand, physical safety of workers can be guaranteed, an rainproof cover can automatically extend outwards on a rainy day, and rain is prevented from dropping on the display screen, so that the service life of the display screen is prolonged.

The invention relates to a reversal displaying device. The reversal displaying device comprises a strip-shaped displaying board body; the strip-shaped displaying board body is provided with two displaying faces, a rotary shaft which is fixedly connected with the two displaying faces separately, a motor and a controller; the displaying faces are provided with LED lamps and driving modules; the controller controls displaying of the two displaying faces separately, and when any displaying face of the two displaying faces is controlled to display and it is judged that the displaying face reaches preset conditions, the motor is controlled to drive the rotary shaft to reverse the strip-shaped displaying board body to transform the positions of the two displaying faces. When one displaying face of the strip-shaped displaying board reaches the preset conditions, the other displaying face is automatically controlled to be replaced for displaying, the displaying face which is 'tired' due to workor is in a 'sub-health state' is allowed to have a rest, the two displaying faces take turns to work for displaying, thus the normal service life of the two displaying faces is prolonged, and then through various preset conditions, the two displaying faces can have various 'rest opportunities' which conform to actual needs.

The invention relates to a turnover box cover locking structure. The turnover box cover locking structure comprises a turnover box body, a box cover and cover locks; the side portion of the upper surface of the box cover is provided with sunken tables I; the tops of side plates of the turnover box body are provided with protrusions, and the protrusions are inserted in sunken tables II formed in the side portion of the lower surface of the box cover; spring bolts convexly arranged on the cover lock sequentially penetrate through the side walls of the sunken tables I and the side walls of the sunken tables II to penetrate into locking notches formed in the side walls of the protrusions; the side surfaces of the cover locks are provided with lock body strip tying holes; and the side walls ofthe sunken tables I are provided with box cover strip tying holes which communicate with the lock body strip tying holes when the sprint bolts are in the locked state. The turnover box cover locking structure has the beneficial effects that the whole locking structure is formed by combining and assembling a few parts, on the premise that stable locking is ensured, the structure is compact and simple, the parts are convenient to replace, and the maintaining cost is reduced.

Embodiments of the present invention provide a display signal processing method and device, and a self-luminous display, which relate to the display field and can improve the display life of pixels in the self-luminous display, thereby improving the display life of the self-luminous display as a whole. The specific scheme is: obtain the RGB grayscale value (X, Y, Z) of the preset pixel, according to the RGB grayscale value (X, Y, Z), and the preset m grayscale coefficient groups (Ui, Vi , Wi), obtain m groups of RGB display grayscale values ​​(Xi, Yi, Zi), according to the m groups of RGB display grayscale values ​​(Xi, Yi, Zi), output m groups of scanning grayscale values, for all The preset pixels are scanned m times continuously in one display period. The invention is used for the display signal processing of the display.
