Abstract

The invention discloses an LED display screen. LED display arrays of the LED display screen comprise a first array and a second array, and a drive device of the LED display screen is provided with a control unit and a drive unit, wherein the drive unit comprises line output and row output which both can form three states under the control of the control unit; an LED anode in the first array and an LED cathode in the second array are connected and jointly connected into the line output of the drive device, and an LED cathode in the first array and an LED anode in the second array are connected and jointly connected into the row output of the drive device; and the dynamic scanning mode of the drive device to the first array is different from the scanning mode to the second array. The invention also discloses a drive method of the LED display screen. In the drive method, the first array and the second array are crosswise driven to work, and the scanning modes of the first array and the second array are different. The invention has the characteristics of cost saving and small occupied space.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to an LED display screen and a driving method thereof. Background technique [0002] LED display screens have been widely used in multimedia portable electronic products such as smart phones, and the displayed content includes text, images, animations and patterns that change with music. Such as figure 1 As shown, the LED display screen 100 includes an LED display array 1 and a driving device 2 for driving the LED display array 1. The driving device 2 usually has several row output controls and several column output controls, and the row output control is used to drive LED display arrays. The row and column output control of the display array 1 is used to drive the columns of the LED display array 1, which is based on the principle of dynamic scanning display, and works in a row or column scanning mode to display the text or image information that needs to be displayed. [0003]...
