Latest Patents

One of Rowley's latest patents is a display device incorporating brightness control. This innovative display device is formed by a matrix of surface-stabilized bi-stable ferroelectric liquid crystal elements, each being separately settable by a matrix driver. To provide brightness control or color in the display, all elements of the matrix are set in accordance with a portion of a signal for display. The amount of light passing through the matrix for that setting is controlled based on the binary significance of the respective portion of the signal. This control is achieved by varying either the activation duration or intensity of a light source, such as sets of fluorescent tubes, in accordance with the binary significance of the brightness information in the input signal. Half of the frame time (T) is utilized for the numerous setting operations on the matrix of elements, while the other half is dedicated to the backlighting operations of the various settings.

Another significant patent by Rowley is related to a discharge tube arrangement. This electrodeless discharge tube contains an ionizable fill and features a first portion for insertion in a launcher, along with a further portion separated from the first portion by a partition wall. This design allows a discharge to be excited in the further portion, as a surface wave can propagate through the wall separating the two portions.
