Touch Sensing Layer Pattern Layout for Low-Reflectance Displays

The patent combines the reflective pattern and light-blocking pattern into a single integrated structure within the touch sensing layer. The reflective pattern (with first reflective layer) and light-blocking pattern (with second reflective layer) are merged such that they share common structural elements and are formed in the same layer, reducing the number of separate components while achieving both light reflection control and light blocking functions.

The touch sensing layer is designed to perform multiple functions simultaneously: it provides touch sensing capability, controls external light reflection through the reflective pattern, and blocks light through the light-blocking pattern. This multi-functional design eliminates the need for separate layers for each function, thereby reducing overall device complexity while improving display efficiency.

The patent applies different dimensional characteristics to different parts of the pattern. The reflective pattern has specific vertical and horizontal lengths optimized for reflecting external light, while the light-blocking pattern has different dimensions optimized for blocking light. This local optimization of dimensions allows each pattern to perform its function effectively without requiring uniform precision across the entire structure.

The reflective pattern and light-blocking pattern are designed with asymmetric dimensions where the vertical length is different from the horizontal length for each pattern. This asymmetric design allows the patterns to be optimized for their specific light control functions rather than requiring symmetric, easier-to-manufacture shapes, thereby achieving superior light control efficiency.
