JCT Electronics Limited is an Indian electronics manufacturing company incorporated in 1976 and associated with the Thapar Group. The company was established to manufacture electronic components, particularly cathode-ray tubes (CRTs) used in television sets and information display systems. Its registered office was located in Mohali, Punjab. The company's historical product portfolio included black-and-white and colour television picture tubes, electronic display components and related products. Its manufacturing operations contributed to India's domestic electronics industry during a period when television manufacturing and electronic display technologies were expanding.
JCT Electronics operated in a specialised segment of the electronics sector, supplying components used by television and display equipment manufacturers. Its business required technical expertise in electronic component manufacturing, production processes and quality control. Over time, changes in display technology, particularly the transition from cathode-ray tubes to LCD and LED displays, transformed the global television and electronics manufacturing industry. These changes affected traditional CRT manufacturers and the markets they served.
