Hong Kong's largest listed liquid crystal display maker, Truly International Holdings, is to boost its annual production capacity for colour super-twist nematic (CSTN) panels for mobile-phones to 60 million units this year. It expects to achieve the target when its new CSTN production line starts operating in May. The firm shipped 12 million panels last year. The group has also developed a camera sensor module and plans to start mass production in June. Chairman Lam Wai-wah yesterday said: 'With extensive usage of CSTN, we expect that [this] business will become the group's main growth driver.' Truly aims to deliver 25 million CSTN panels to South Korea this year to enhance its market share. Mr Lam said a European telecommunications firm with handset factories in Europe and Central and South America has contracted Truly to supply CSTN modules. 'We are working to add two more telecommunications companies and European brands to our customers list this year. Our target shipment to Europe is two to four million CSTN modules.' Truly was also actively studying the application of CSTN in MP3 players, cordless phones, portable game players and other digital electronic products, Mr Lam said. Truly announced a 173.29 per cent jump in net profit to $526.5 million last year. Turnover surged 143.37 per cent to $3.4 billion. Earnings per share were $1.18, against 43.4 cents previously. The firm declared a final dividend of 23 cents a share, up from 12 cents a year ago. Shares of Truly fell 5.38 per cent to $10.55 yesterday.
