The matricon cathode-ray tube

The conventional cathode-ray tube has many disadvantages when used for the display of alphanumeric data-mainly because of its dimness. It has been estimated that the brightness produced by a Matricon display is 20 times higher than is possible using an ordinary cursive system. Recently, c.r.t.s. containing line-Matricon-type guns have been used to produce linear displays from thermographic equipment.
