Micro LED Display Panel Optical Modulation Structure

The patent applies the dynamics principle by using a switchable optical modulation structure that can dynamically change between a first state and a second state. In the first state, a first light-emitting unit forms an image at a first position, and in the second state, the same light-emitting unit forms an image at a second position. This dynamic switching creates multiple virtual image positions from a single physical light-emitting unit, effectively increasing the perceived pixel density without adding more physical units, thereby avoiding the manufacturing cost increase and quantum efficiency decline associated with higher density LED arrangements.

The patent applies the dimensionality change principle by introducing a spatial dimension through the optical modulation structure. Instead of increasing pixel density in the traditional two-dimensional plane by adding more light-emitting units, the patent creates a third dimension of image positioning by shifting images between different positions (first position and second position) through optical modulation. This allows the system to achieve higher effective PPI by utilizing spatial positioning in the optical path rather than simply packing more LEDs closer together.

The patent applies the copying principle by creating virtual copies of light-emitting unit images through optical modulation. The optical modulation structure generates multiple image positions (first position and second position) from a single physical light-emitting unit, effectively creating virtual copies of the light source. This allows the display to achieve higher effective pixel density using the same physical LEDs, avoiding the quantum efficiency degradation that occurs when physically smaller LED chips are used to increase density.

The patent applies the universality principle by designing an optical modulation structure that serves multiple functions: it can switch between different optical states, modulate light paths, and create multiple image positions from a single light-emitting unit. This multi-functional structure replaces what would otherwise require multiple separate light-emitting units and their associated control circuits, thereby achieving higher effective PPI while actually reducing the overall device complexity and number of components.
