Corner Reflection Members for Display Luminance Uniformity

The patent applies local quality by providing reflection members specifically at the four corner regions where luminance is insufficient, rather than using a uniform reflection structure across the entire casing. Each reflection member is positioned and oriented to reflect light toward its corresponding corner, creating localized light enhancement where it is most needed.

The patent segments the reflection function by providing separate reflection members for each of the four corners rather than using a single continuous reflection surface. This segmentation allows independent optimization of light reflection for each corner region, addressing the specific luminance deficiency at each corner.

The patent maintains the simple direct backlight structure while adding localized reflection members only at the four corners. This approach preserves the overall structural simplicity of the direct backlight module while addressing the specific luminance unevenness problem at the corners through localized optical modification.

Instead of modifying the entire backlight structure, the patent applies partial action by adding reflection members only at the four corner regions where luminance enhancement is needed. This partial modification achieves the desired luminance uniformity without the complexity of a complete structural redesign.
