Abstract

The invention discloses a backlight source and a backlight source system. The backlight source comprises a plurality of white lamps and a plurality of colored lamps. The white lamps are connected in series at second intervals in the second direction to form white lamp series sets. The white lamp series sets are connected in parallel at first intervals in the first direction. The colored lamps are connected in series at twofold second intervals in the first direction to form colored lamp series sets, and the colored lamp series sets are connected in parallel at twofold second intervals in the second direction. The first direction is perpendicular to the second direction, and the distances between any colored lamp and the adjacent four white lamps are equal. The backlight source meets the requirement for night vision in a night working mode, and meets the high-brightness requirement in a daytime working mode.

Description

technical field [0001] The present invention relates to the display field, in particular to a backlight source and a backlight source system. Background technique [0002] In the modern military field, night vision compatible technology has an important position, and it is applied to various night vision weapons and equipment and night vision combat platforms on sea, land, air, and aerospace. On the equipment with night vision imaging system, each display system or illuminant equipment must meet the night vision compatibility requirements to ensure naked eye visibility and non-interference with each other. [0003] The backlight or backlight system of a night vision compatible LCD display can not only work in full day mode, but also will not emit light and energy that interfere with the use of night vision equipment at night or in weak light conditions, ensuring the normal use of the display equipment and Take advantage of night vision. When working at night, the display i...
