| titleOfInvention | Method and device for eliminating water ripples of display panel and display device |
| abstract | The invention provides a method and a device for eliminating water ripples of a display panel and a display device, wherein the method for eliminating the water ripples of the display panel comprises the following steps: acquiring the modulation frequency and the modulation amplitude of spread spectrum, and calculating the modulation period T of the spread spectrum according to the modulation frequency of the spread spectrum; discretizing the modulation amplitude in one modulation period of the spread spectrum to obtain N discretization modulation amplitude values, wherein N is a positive integer; under the condition of receiving a frame start signal, generating N different addresses, and randomly allocating the N addresses as storage addresses of the N discrete modulation amplitude values; and sequentially reading and outputting the discretization modulation amplitude values according to the sequence of the N addresses. According to the elimination method provided by the embodiment of the invention, the electromagnetic interference requirement of the display device is met, and meanwhile, the modulation amplitude is discretized and converted into the disordered spread spectrum amplitude value for outputting, so that the pixel charging rate Jitter value can be randomly changed, and the water ripple phenomenon of the display panel is eliminated. |
