The invention is applicable to cathode ray tubes.

The device (10) comprises three CRT's (16(a-c)).

Circuitry is disclosed for linearizing the image reproduction by cathode ray tubes.

The modulator is for use in display tubes, particularly for projection TV.

A method of making a building product material from hazardous recycled Cathode Ray Tube glasses.

Dynamic adjustment techniques for aligning video images in cathode ray tube (CRT) devices (12) are disclosed.

A phosphor powder based on manganese-doped zinc silicate (Zn2SiO4:Mn), with an average particle size of less than 20 micrometres and a decay time of less than 7 ms.

The displays preferably selected among CRT, EL and LCD systems.

A production method is also provided and comprises mixing zinc oxide, silica and manganese sulphate in an aqueous medium, drying the mixture and curing it at 1200-1400 °C. Said phosphor is suitable for use in cathode ray tubes.
