Latest Patents

Furukoshi's latest patents include a driving method and drive control circuit for liquid crystal display devices. This drive control circuit features a timing controller that detects changes in horizontal scanning frequency. It also includes a gate voltage generating circuit that produces two types of gate-on voltages, Va and Vb, with Va being less than Vb. The timing controller utilizes a counter to track clock counts for one horizontal period and a comparator to assess these counts against a threshold value. When the horizontal scanning frequency is normal, the low gate-on voltage Va is used. However, if the frequency exceeds a predetermined threshold, the high gate-on voltage Vb is activated.

Another notable patent involves an illumination device and liquid crystal display device that utilizes a unique method of modulating light transmissivities across multiple pixels. This device includes an LCD panel that adjusts light based on gradation data, an illumination device that changes the duty ratio of lighting time, and a display data conversion part that processes gradation data to optimize display performance.
