The light is emitted in a direction perpendicular to the optical module 102.
由于显示屏组104发出的光比拼接缝反射的光强，因此，显示屏组104发出的光会对拼接缝反射的光在视觉上产生遮盖效果，从而在视觉上消除了拼接缝处形成的反光区域。Since the light emitted by the display panel 104 is stronger than the light reflected by the splicing seam, the light emitted by the display panel 104 visually occludes the light reflected by the splicing seam, thereby visually eliminating the splicing seam.
