The design creates more brightness through increased electron transmissions combined with the arrangement of the phosphor dots. A CRT device delivers tiny amounts of electrical energy to the heart through these leads. Unfortunately, manufacturers are not always upfront about dot pitch measurements, and you cannot necessarily compare shadow-mask and aperture-grill CRT types, due to the difference in horizontal and vertical measurements.
