Problems solved by technology

However, its single-color screen or two-color screen can only display characters and graphics, and cannot display images. Although full-color screens can display images, the cost is extremely high, and the cost of several million or even tens of millions limits most of them. The scope of application; and its display effect is not good, the color reproduction is lower than other display methods, especially the display resolution is difficult to achieve high definition, unless the display size is large enough, the display pixels are sufficient, and the viewing distance is far enough, but The cost and cost of this will often be very high

Embodiment Construction

[0037] The outdoor large-screen display device of the present invention considers the two operating conditions of high ambient illuminance during the day and low ambient illuminance at night in view of the characteristics of daytime display and nighttime display. In view of the characteristics of high-illuminance display during the day, low-cost spray-painted images are used instead of electronic image display to avoid the contradiction between high-brightness display necessary for high-illuminance and high display cost. In order to greatly increase the amount of advertising information and improve the display effect of (inkjet) images during the day, an automatic switching system for inkjet pictures is designed so that it can automatically play any number of advertising pictures in a loop, greatly improving the monotonous effect of ordinary advertising screens. Make full use of low-light conditions at night, adopt large-screen display technologies (front projection, rear proje...
