Latest Patents
One of Halls' latest patents is for an electroluminescent display and driver circuit designed to reduce photoluminescence. This invention relates to display driver circuits for electro-optic displays, specifically targeting the reduction of re-emission of absorbed light. The goal is to increase the color gamut of OLED displays. The driver comprises addressing circuitry to manage a plurality of light-emitting diode display elements. It includes a first driver that cooperates with the addressing circuitry to provide forward drive to illuminate at least one display element. Simultaneously, a second driver provides a reverse bias drive to other display elements, effectively reducing photoluminescence from those elements.
Another significant patent involves optoelectronic displays, which describes apparatus and methods based on photoluminescent quenching. This method includes providing an optoelectronic display with photoluminescent material situated between two electrodes. The process involves illuminating the photoluminescent material to induce photoluminescence while biasing the electrodes to partially quench this photoluminescence.
