Brightness control D/T conversion technology

LED electronic display is composed of many independent pixels by arrangement and combination. Based on the feature of separating pixels from each other, LED electronic display can only expand its luminous control driving mode through digital signals. When the pixel is illuminated, its luminous state is mainly controlled by the controller, and it is driven independently. When the video needs to be presented in color, it means that the brightness and color of each pixel need to be effectively controlled, and the scanning operation is required to be completed synchronously within a specified time.
Some large LED electronic displays are composed of tens of thousands of pixels, which greatly increases the complexity in the process of color control, so higher requirements are put forward for data transmission. It is not realistic to set D/A for each pixel in the actual control process, so it is necessary to find a scheme that can effectively control the complex pixel system.

By analyzing the principle of vision, it is found that the average brightness of a pixel mainly depends on its bright-off ratio. If the bright-off ratio is effectively adjusted for this point, the effective control of brightness can be achieved. Applying this principle to LED electronic displays means converting digital signals into time signals, that is, the conversion between D/A.
