Problems solved by technology

[0007] The purpose of the present invention is to provide a method for realizing clock control by using pulse modulation, aiming to solve the problem of high display accuracy when the display driving method for LED display control provided by the prior art displays pictures on a dynamic screen. In some cases, the refresh rate is low, which makes the displayed picture poor in stability and poor in user experience.

Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] Aiming at the problem in the prior art that the display accuracy is inversely proportional to the refresh rate, which cannot meet the high refresh rate under high display accuracy, the method of implementing clock control by using pulse modulation provided by the embodiment of the present invention is to divide the original display data, and according to The divided display data generates a PWM signal with a corresponding duty cycle for adjusting the display effect.

Abstract

The invention is applicable to the field of display technology and provides a method and a system for realizing clock control by use of pulse modulation. The method comprises the following steps of: receiving original display data which comprises at least one original row data; dividing each original row data in the original display data into multiple row data; generating multiple PWM (pulse width modulation) signals with a duty cycle corresponding to the row data; and outputting the multiple PWM signals to a display device. In the method for realizing clock control by use of pulse modulation provided by the embodiment of the invention, the original display data is divided, and the PWM signals with corresponding duty cycle for adjusting the display effect is generated according to the divided display data so as to drive the image display of an LED (light emitting diode) or other display devices and improve the refresh rate of dynamic display while ensuring the high-accuracy display; and meanwhile, the clock of the PWM signal is processed according to the data weight bit of the divided row data, thus the pressure on data storage and processing is reduced.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a method and system for realizing clock control by using pulse modulation. Background technique [0002] As governments around the world reach a consensus on green energy conservation and environmental protection, LED display technology has become one of the high-tech fields with the most potential for development. LED is a device with constant current characteristics. This type of device is extremely sensitive to voltage and is not easily controlled by voltage. By controlling the current flowing through the device, its brightness can be controlled more accurately. [0003] The traditional display driving method for LED display control is to use an external resistor to control the current flowing through the LED, control the LED on and off within the display time period through the display data, and control the display time through the output enable switch. Length, so as to ach...
