JCT Electronics Limited (JCTEL) was the first Colour Picture Tube (CPT) manufacturer in India. JCTEL, formerly known as Punjab Display Devices Limited (PDDL), was set-up as a wholly owned subsidiary of Punjab State Industrial Development Corporation (PSIDC) in 1976, to manufacture Black & White Picture Tubes, Cathode Ray Tubes, Gas filled Discharge Tubes and Fluorescent Display Tubes at Mohali, Punjab, India.

PDDL was taken over in 1986 by JCT Ltd, a flagship Thapar Group Company, as a diversification project to manufacture CPTs and therefore renamed as JCTEL. JCTEL thereafter setup a modern plant for manufacture of CPTs in technical collaboration with Hitachi, Japan, one of the pioneers in the Display Devices. Initially the plant had a capacity of 0.6 Million CPTs, which is now rated at 1.0 Mil PA.

In 1996, JCTEL went in for an expansion and set-up a new Greenfield plant near Vadodara, in Western India. Engineered in-house with Hitachi's assistance, to manufacture 1 Million (presently at 1.8 Million) CPTs PA of sizes 14", 20" and 21". Propose to introduce 21" Pure Flat very shortly.
