Embodiment Construction

[0025] In the various embodiments listed below, the same or similar elements or components will be denoted by the same reference numerals.

[0026] figure 1 It is a schematic diagram of a display device according to an embodiment of the present invention. Please refer to figure 1 , the display device 100 includes a display module 110 and a control device 140 . The display module 110 includes a plurality of display units 120_1˜120_N, wherein N is a positive integer greater than 1. Each display unit 120_1˜120_N includes a plurality of pixel units 120_1_11˜120_N_XY.

[0027] For example, the display unit 120_1 includes pixel units 120_1_11, 120_1_12, . . . , 120_1_1Y, 120_1_21, 120_1_22, . The display unit 120_2 includes pixel units 120_2_11, 120_2_12, . . . , 120_2_1Y, 120_2_21, 120_2_22, . The display unit 120_N includes pixel units 120_N_11, 120_N_12, . . . , 120_N_1Y, 120_N_21, 120_N_22, .

[0028] In addition, X and Y are positive integers greater than 1, and X is the ...

Abstract

The invention provides a control device, a display device and an operation method thereof. The control device includes a signal-output device, a signal modulation device, a storage device, and a processing device. The signal-output device outputs a plurality of data signals. The signal modulation device outputs a plurality of modulation signals. The storage device is coupled to the signal-output device and stores a large amount of display data. The processing device is coupled to the signal-output device and the signal modulation device. The processing device controls the signal-output device so that the signal-output device divides the display data and transforms the display data into the data signals according to the repeat performing number and the moving position region, so as to sequentially output the data signals. The processing device controls the signal modulation device, so that the signal modulation device sequentially outputs the modulation signals according to the pulse wave counting number and the pixel unit number.

Description

technical field [0001] The embodiments of the present invention relate to a control device, in particular to a control device, a display device and an operation method thereof. Background technique [0002] Due to the increasing size of modern light emitting diode (LED) display screens, most LED display screens use multiple small LED modules arranged to form a large display screen. [0003] Generally speaking, image data needs to be divided through the control chip outside the module. In the traditional design, a high-end processor (central processing unit, CPU) or a field programmable logic gate array (field programmable gate array, FPGA) is required to divide and process data to drive multiple LED modules. However, the cost of high-end CPU and FPGA is high, and the number of LED modules that can be driven is limited, and the display screen may have asynchronous problems. Therefore, how to improve the driving method of a plurality of LED modules will become a subject that...
