rCore Strengths

We have a dedicated team of professional engineers who are based on our state-of-the-art R & D Research department. Our R & D team has the right expertise and teh ease of access to the latest technological platforms required to lead, enhance and make sure we remain the best breed. We possess a wide range of patented intellectual property rights and over 7 years in existence deveoped a myriad of technological platforms which we implemented over our range of products, such as in the early doption of PWM technology compared with other manufaturers, and the serious implementation of the Dot-to-Dot calibration.

Research and Deveopment Policy

It has been the prime objective of the HanJing management to ensure the continual capability for innovate in order to live up to with customers' expectations and specific market requirements. Our policy and practice is to make sure each year a minimum of 6% of our revenue is being reinveted into R & D department.

a. Full Brightness Adjustment with Intact Levels of Grey Scale

We are the first adopter of the Pulse Width Modulation (PWM) Technology in the led display industry. By applying the PWM technology over HanJing led display system the in-build level of gray-scale is virtually hard-wired and remained intact even if we vary the input level of the constant current supply source. Hence with the number of pray-scale levels remaining intact under changing current level condition due to ambience sensors f.i. the image retains its swiftness and smoothness. When translated into daily life, this feature is especially instrumental and visually beneficial to owners and viewers of the display when the ambient auto-brightness sensing is frequently triggered in a mundane routine.
