Description

Technical Field

[0001] The present invention relates to the field of display screen technology, and in particular to a glass-based Mini-LED grayscale control system, method, device and storage medium. Background Art

[0002] At present, glass-based Mini-LED uses PWM dimming to control the brightness of the LED. The LED is turned on by adjusting the switching frequency of the MOS tube, and the brightness is controlled by modulating the PWM duty cycle to achieve different grayscales.

[0003] In the related technology, the grayscale resolution distribution corresponding to the voltage level and PWM waveform of the back stage is usually determined first, and then converted into the PWM waveform required to be output by the front-stage Tcon chip and the instructions required to be issued to the back stage, and debugged to form a table stored in the Tcon chip. That is, when determining the grayscale to be output, the Tcon chip obtains the PWM waveform required to be output by looking up the table, and issues the corresponding instructions to the DC control module, prompting it to output the corresponding voltage to the level conversion module for it to convert the PWM waveform. After completing these steps, the final PWM waveform will be given to the LED Driver IC to further drive the Mini-LED to emit light.

[0004] However, the PWM waveforms in the above-mentioned manners are all subjected to several modulations before being finally outputted. During these processes, the waveforms are easily damaged and the levels are also affected, thus causing the grayscale output to be affected by the waveforms. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] At present, glass-based Mini-LED uses PWM dimming to control the brightness of the LED. The LED is turned on by adjusting the switching frequency of the MOS tube, and the brightness is controlled by modulating the PWM duty cycle to achieve different grayscales.

[0026] At present, it is usually necessary to first determine the grayscale resolution distribution corresponding to the voltage level of the back stage and the PWM waveform, and then convert it into the PWM waveform that the front-stage Tcon chip needs to output and the instructions that need to be issued to the back stage, and debug it to form a table and store it in the Tcon chip. That is, when determining the grayscale that needs to be output, the Tcon chip obtains the PWM waveform that needs to be output by looking up the table, and issues the corresponding instructions to the DC control module, prompting it to output the corresponding voltage to the level conversion module for it to convert the PWM waveform. After completing these steps, the final PWM waveform will be given to the LED Driver IC to further drive the Mini-LED to emit light. However, the PWM waveforms in the above method are all subjected to several modulations before they are finally output. In these processes, the waveform is easily damaged and the level will also be affected, resulting in the grayscale output being affected by the waveform.

[0027] In response to the above problems, the embodiments of the present application provide a grayscale control system, method, device and storage medium for glass-based Mini-LED, which can reduce the attenuation caused by the PWM waveform transmission process, thereby stabilizing the grayscale output.

[0028] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

The acquisition module 100 is used to obtain required grayscale data; the main control module 200 is used to receive grayscale data, and output a PWM waveform and a voltage regulation instruction according to the grayscale data; the driver integration module 300 is used to receive the voltage regulation instruction, convert the PWM waveform, and output a real-time PWM waveform to drive the Mini-LED to emit light.

[0030] It should be noted that the acquisition module 100 is used to acquire the grayscale that needs to be output, the main control module 200 is a TCON chip, and the driver integration module 300 has the functions of level conversion, voltage regulation and output voltage, that is, all processing for the PWM waveform is completed in one module, and there is no need for multiple modules to receive responses, thereby avoiding the attenuation of the PWM waveform and stabilizing the grayscale output.

[0031] Specifically, the driver integration module 300 includes a multi-stage voltage regulation unit, which is used to receive a voltage regulation instruction and generate a regulation voltage.

[0032] It should be noted that the multi-level voltage regulating unit outputs the voltage required for each voltage level and provides it to the subsequent level conversion module for reference, and it has no actual load.

[0033] Specifically, the driver integration module 300 further includes a level conversion unit, which is used to receive a regulation voltage, convert a PWM waveform according to the regulation voltage, and generate a real-time PWM waveform.

[0034] It should be noted that the function of the level conversion unit is to convert the PWM signal output by the Tcon chip. The converted PWM waveform is only the function of the switching TFT and also has no actual load.

[0035] Specifically, the driver integrated module 300 also includes an LED chip unit, and the LED chip unit is used to output a real-time PWM waveform to the Mini-LED to drive the Mini-LED to emit light.

[0036] It should be noted that the LED chip unit is used to output the PWM waveform to the Mini-LED to drive the Mini-LED to emit light.

[0037] In this way, the driver integrated module of the present application has the functions of level conversion, voltage regulation and output voltage, that is, all processing of the PWM waveform is completed in one module, without the need for multiple modules to receive responses, thereby avoiding attenuation of the PWM waveform and stabilizing the grayscale output.
