Future trends and trends of LED display-by-point correction technology

LED display point-by-point calibration technology future development trend

LED display expert introduction point by point correction in the late 90s to 2008 nearly 10 years of the bud, after the rapid growth of 2008-2010 three years, will soon be in the process of accumulation of theory and practice, in the division of labor further In the process of refinement, process standardization, agreement unification, and assessment standardization, it gradually entered its mature stage.

First, the technical division of labor is further refined and specialized

With the trend of increasingly detailed and specialized industrial division of labor, the point-by-point calibration acquisition equipment also shows a trend of separation from the control system and increasingly specialization.

With the pursuit of high quality and the promotion of market competition, more and more companies are adopting professional point-by-point calibration acquisition equipment to solidify the point-by-point calibration into a standard process process, not just the product of quality problems. Policy. Only professional subdivision can achieve wide compatibility, and in order to enable professional teams to continue to focus on deepening cultivation, complementary resources, and promote technological progress.

Second, faster, easier, automated, standardized

Point-by-point calibration technology It takes one month to calibrate a large screen from the initial stage, and the development of today's nearly 200-square-pixel large-screen correction has been completed overnight, and has achieved epoch-making progress. The point-by-point correction of the future will continue along the route of high efficiency, simplicity, automation and standardization, which is an inevitable trend determined by industry demand. On the road to achieving this goal, in addition to the technological innovations of the acquisition equipment, the cooperation and support of industry control system partners, the construction and promotion of industry standards, and the experience accumulation and exchange of point-by-point correction practitioners are more needed.

Third, data storage to the module

LED display manufacturing industry has always been the order production model, and now many large companies are beginning to explore a planned production model. On the one hand, they can shorten the supply cycle to create a competitive advantage. On the other hand, standardized production can be managed on a scale basis. Generate benefits and competitive advantages. Planned production means modular or standard tank inventory, which means the diversity of the combinations at the time of shipment.

To meet the requirements of planned production, the excellent data storage method for point-by-point correction is placed on the module, rather than on the receiving card of the control system as much as now. When the module or box is assembled into a display screen, the control system reads back the correction data on the module, or reads back the original data and generates a correction coefficient based on the corrected target value, and applies it. This kind of technical structure will make the maintenance of data after the replacement of the module a breeze. In fact, the famous LED screen manufacturers at home and abroad adopt this kind of calibration data storage method.

However, to achieve this goal, it is still necessary to form a unified data communication protocol between the control system and the module within the industry.

Xi'an LED display is gradually accepted by the market for its energy saving, environmental protection, and highlights. Which has been widely used in advertising leasing market, Expo exhibitions, entertainment interpretation and other fields. LED display technology has not only been applied on municipal traffic guidance cards, but has also developed into the direction of automotive light sources and illumination light sources. Popularly speaking, this is a more energy-efficient and environmentally friendly "service-oriented" technology product. In order to promote the development and application of point-by-point correction technology, it is the finishing touch for the LED display industry.
