Latest Patents
Among his latest innovations, Vriens holds two notable patents related to CRT technology. The first patent, titled "CRT with Improved Slotted Mask", describes a cathode ray tube featuring a tensioned shadow mask equipped with slits that vary in number depending on the application—between 160-180 or 210-240 slits per row. This innovation is particularly useful for CRTs with screen sizes larger than 21 inches, as it offers a substantially Moire-free image for NTSC, PAL, and VGA signals. The second embodiment caters to smaller CRTs with sizes of 23 inches or less, designed for CMT applications, and provides a similar Moire-free image for SVGA and XGA signals.
Vriens's second patent also titled "CRT with Improved Slotted Mask", introduces a cathode ray tube that features elongated holes in its tensioned shadow mask. These holes exceed 5 mm in length and create a repeating pattern after five or more rows. The patent outlines an optimal relation among the number of rows, vertical pitch (a), and horizontal pitch (d), establishing a framework for enhancing display clarity and performance.
