Abstract
Description
technical field
[0001] The invention relates to the field of display technology, in particular to an exposure device and an exposure system. Background technique
[0002] In the manufacturing process of the display panel, a mask exposure process is often required. figure 1 It is a schematic diagram of the optical path of the proximity exposure equipment. In the actual mask exposure process, such as in proximity exposure equipment, such as figure 1 As shown, the illuminance distribution of the ultraviolet light projected on the equipment base from the high-pressure mercury lamp is uneven, and with the prolongation of the high-pressure mercury lamp, the illuminance distribution of the ultraviolet light projected on the equipment base also changes with time , resulting in a large difference in line width at different positions of the exposed product, and poor line width uniformity.
[0003] In addition, in the mask exposure process, the bending deformation of the mask plate ...
