Current Adjustment Compensates the Brightness Non-uniformity It is known that LED degradation with time results in the loss of the LED brightness. To ensure the video quality, maintaining the uniformity of LED therefore becomes especially important for LED display applications. However, it is inevitable that LED degrades with time. Macroblock, therefore, introduces LED drivers with current-adjustable function, an LED brightness compensation solution. That is, such drivers can adjust the average current to equalize the uniformity of the LED display panel from the beginning to the end. In addition, the maintenance engineers can easily compensate the degraded LED online by adjusting the current through a user-friendly computer link. To achieve and maintain excellent LED video quality, the customer chose Macroblock's such user-friendly solution and benefited from reducing the maintenance cost.
