Latest Patents

Gogna's latest patents include groundbreaking technologies that enhance display performance. One of his patents is for an electro-optical display having a split storage capacitor structure for series capacitance. This invention features a matrix array of picture elements and a thin film structure of storage capacitors associated with each picture element. The design incorporates redundancy in the storage capacitor structure by segmenting one of the capacitor plates into two plates, producing two capacitors in series. This innovative approach eliminates the need for additional masking steps, as the segmented plates are all on one level of the thin film structure.

Another significant patent is for a reflective liquid crystal display having integral light shielding. This technology includes an array of reflective pixels located over a silicon substrate surface, with light transmissive regions situated between the reflective pixels. The structure features two metal layers that form row and column electrodes of the LCD. To block light that would otherwise pass through the light transmissive regions, portions of the metal layers extend beneath these regions, providing a light-blocking function without requiring a separate blocking or shading metal layer.
