Description

Technical Field

[0001] The present invention relates to the field of display processing, and in particular to a method for processing instantaneous display abnormality. Background Art

[0002] As doctors' demand for accurate diagnosis of patients increases, the display performance requirements of medical displays are gradually increasing. Display resolution is gradually increasing to FHD resolution (1920*1080) and UHD resolution (3840*2160), which requires higher speed and higher quality image signals. However, unstable quality of high-speed video signals or abnormal interference such as ESD will cause short-term screen distortion, 1 to 4 seconds of black screen, half screen and other abnormal problems. Momentary image abnormalities will seriously affect the patient's surgical process and diagnosis results, and may even endanger the patient's life. Summary of the invention

[0003] The purpose of the present invention is to provide a method for processing instantaneous display anomalies, aiming to solve the problem of short-term screen distortion and black screen caused by unstable high-speed video signal quality or abnormal interference such as ESD.

[0008] The image processing chip is used to convert high-speed image data into images and send them to the display for display;

[0009] The memory is used to store the high-speed image data;

[0010] The method comprises:

[0011] When the image processing chip obtains ESD abnormality information or abnormal high-speed image data detected by the power supply circuit, it reads the high-speed image data segment before the preset number of frames from the current one from the memory, and outputs it to the display for display.

[0012] Preferably, the number of image frames included in the abnormal high-speed image data is smaller than the number of image frames included in the high-speed image data segment.

[0014] The advantages of the present invention are:

[0015] The method for processing instant display abnormalities provided by the present invention can effectively solve the short-term screen distortion and black screen problems caused by unstable high-speed video signal quality or abnormal interference such as ESD. There is no obvious abnormality in the display, and the human eye cannot perceive the instant abnormality, ensuring stable display reliability during long-term lighting or multiple power on and off processes, ensuring the normal use and diagnosis needs of doctors. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 is a schematic block diagram of an image display device of the present invention;

[0017] Figure 2 It is a flow chart of a method for processing instant display abnormality of the present invention. DETAILED DESCRIPTION

[0018] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0019] This embodiment provides a method for processing instant display abnormality, which is applicable to an image display device, such as Figure 1 As shown, the image display device includes a display, an image processing chip, a power circuit and a memory, and the image processing chip, the power circuit and the memory are installed on a mainboard. The power circuit is electrically connected to the image processing chip to provide power to the image processing chip and the display, and the image processing chip is electrically connected to the memory and the display respectively. The power circuit can detect ESD abnormal information and send it to the image processing chip. The image processing chip can identify the ESD abnormal information of the power circuit and store the current high-speed image data in the memory.

[0020] In normal working mode, the image processing chip is used to convert high-speed image data (such as HDMI, DVI, DP, 12G SDI, etc.) into images and send them to the display for display. The display is a display device. The memory is used to store high-speed image data. The memory is a temporary storage device for storing high-speed image data processed by the display, which can be understood as a backup device for normal high-speed image data. The memory is a RAM / Flash memory.

[0021] When ESD and other abnormal interferences cause the voltage of the power supply to fluctuate greatly or the current to be high, it will cause abnormal display of the screen such as flashing, black screen, and distorted screen. In addition, when the quality of external high-speed image data deteriorates, the image will fluctuate, causing abnormal display of the screen such as flashing, black screen, and distorted screen. In order to solve this phenomenon, Figure 2As shown, the method for handling the instant display abnormality includes:

[0022] When the image processing chip obtains ESD abnormal information or abnormal high-speed image data detected by the power supply circuit, it reads the high-speed image data segment before the preset number of frames from the current time from the memory and outputs it to the display for display. The number of image frames included in the abnormal high-speed image data is less than the number of image frames included in the high-speed image data segment.

[0023] For example, when the image processing chip recognizes the above abnormality, a high-speed image data segment 50 frames before the current one is read from the memory to ensure that the read data is normal high-speed image data. The number of image frames contained in the high-speed image data segment is as far greater as possible than the number of image frames contained in the abnormal high-speed image data.

[0024] It is understandable that when the image processing chip recognizes an abnormality, it can quickly retrieve the most recently stored normal display data from the RAM / Flash storage device and output it to the display screen to cover the previous abnormal image data. The time difference makes it difficult for the human eye to recognize. After the abnormal display mode returns to normal, it switches back to the normal working mode. Based on this, the short-term screen distortion and black screen problems caused by unstable high-speed video signal quality or abnormal interference such as ESD can be effectively solved.

[0025] The above are preferred embodiments of the present invention and the technical principles used therein. For those skilled in the art, any obvious changes such as equivalent transformations, simple replacements, etc. based on the technical solution of the present invention, without departing from the spirit and scope of the present invention, are within the scope of protection of the present invention.
