Latest Patents

One of Wan-jae Son's latest patents is an innovative electron gun for cathode ray tubes. This design features a second of three focusing electrodes that is divided into first, second, and third auxiliary electrodes. By applying a first dynamic voltage synchronous with vertical and horizontal deflection signals to the first and third auxiliary electrodes, and a second dynamic voltage to the second auxiliary electrode, the design enhances the performance of the electron gun. The use of two dynamic focusing voltages in a low voltage driving method significantly reduces the risk of arc discharge between electrodes and compensates for astigmatism in the electron beam. This results in a sharper picture by improving the focusing of the electron beam.

Another patent by Son involves an electron gun that includes a cathode, control grid, screen grid, and an opposed anode and focus electrode. This design controls and accelerates multiple electron beams, featuring recesses with aligned central beam passing holes and pairs of peripheral beam passing holes. The innovative arrangement of the peripheral beam passing holes, which are inclined relative to the electron beam passing direction, further enhances the efficiency of the electron gun.
