Embodiment Construction
[0051] The embodiment of the present invention provides a method and device for calibrating the entire screen of an LED display screen, which is used to solve the problem that the LED particles of the strongest optical signal that can be collected by the optical signal collection device are in the normal direction that coincides with the position of the collection device. The design of the LED particles of the light signal in the normal direction of the light output causes the technical problem of the unevenness of the collected light information, and greatly expands the viewing angle range of the LED splicing screen.
[0052] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the following The described embod...

The embodiment of the present invention discloses a full-screen correction method and device for an LED display screen, which are used to solve the problem that the LED particles with the strongest optical signal that can be collected by an optical signal collection device are in the normal direction that coincides with the position of the collection device. The design of the LED particles of the light signal in the normal direction of the light output leads to the technical problem of the non-uniformity of the collected light information, and greatly expands the viewing angle range of the LED splicing screen. The method of the embodiment of the present invention includes: classifying several splicing units according to the light information value from high to low, and arranging the positions of the splicing units from the outside to the inside according to the classification of the grades to form a whole screen; The light information of the whole screen is collected and corrected according to the collected light information.
Description
Technical field [0001] The present invention relates to the technical field of optical signal processing, in particular to an entire screen correction method and device of an LED display screen. Background technique [0002] With the rapid development of technology and the growth of large market demand, large-scale LED displays, such as LED splicing screens, are becoming more and more popular. LED splicing screens usually consist of several splicing units, and each splicing unit is arranged with several Each LED particle, for example, a 12 square centimeter splicing unit will arrange approximately 6,400 LED particles. Because the factory specifications of each LED particle and its hardware light emission specifications are inconsistent, it is necessary to check all the LEDs on the LED display. The brightness and color of the particles are corrected on the whole screen. [0003] At present, for the entire screen correction technology of LED splicing screens, the light signal collec...
