Description

Technical Field

[0001] The utility model relates to a display device comprising an optical sensor, belonging to the technical field of display devices. Background Art

[0002] Compared with ordinary display devices, professional medical display devices not only have higher resolution, higher brightness and higher contrast, but also have a grayscale display brightness response curve correction function that complies with the DICOM (Digital Imaging and Communications in Medicine) standard (hereinafter referred to as DICOM curve).

[0003] Grayscale refers to the limited number of brightness divisions of the display device from the blackest to the whitest. Currently, display devices are generally divided into 256 grayscales, named grayscale 0 to grayscale 255. The corresponding relationship between grayscale and brightness from low to high is called the grayscale brightness response curve. The brightness of grayscale 255 is called white field brightness, which is generally limited to the maximum brightness that the display device can achieve.

[0004] The physiological characteristics of the human eye are that when the brightness of the image being viewed is low, a small change in brightness can be noticed by the human eye; when the brightness of the image is high, a large change in brightness is required to be noticed by the human eye.

[0005] The principle of the DICOM curve is to correct the brightness of the 256 grayscales of the display device according to the characteristics of the human eye, so that there are small but sufficiently resolvable brightness changes between the grayscales in the low-brightness low-grayscale part, and there are large brightness changes between the grayscales in the high-brightness high-grayscale part. In this way, the 256 grayscales can be distinguished from each other by the human eye, and there will be no visual grayscale loss, ultimately obtaining accurate medical image browsing and diagnosis results.

[0006] In actual use, it is found that most of the existing medical professional display devices use LED backlight LCD screens or organic light-emitting OLED screens. During long-term use of such display devices, the LED backlight, the polarizer of the LCD screen, and the organic light-emitting material of the OLED will age, causing the final display brightness to decay or the color to change. In order to ensure the compliance of the DICOM curve, the existing medical professional display devices will install a brightness sensor on the back of the LCD screen, called a backlight sensor, which is used to detect the brightness of the LED backlight in real time and make compensation and adjustments; and install a brightness and color sensor on the front of the display device, called a front sensor, which is used to detect the brightness and color of the LCD screen and perform quality control regularly.

[0007] Currently, with the development of mobile Internet, considering the trend of globalization and force majeure factors such as epidemics, severe weather, and geological disasters, medical workers hope to have more convenient office equipment so that they can view patients' medical imaging data at home or on the road.

[0008] In this case, more medical display devices will develop in the direction of being light, thin and portable. At this time, the portable flat-panel display or tablet computer will no longer be able to provide the function of the front sensor, because the front sensor needs to protrude from the surface of the screen, which will have a greater impact on the appearance and structure of the tablet-type display or computer. As a result, there are currently no products or solutions with embedded front sensors on tablet computers or flat-panel displays.

[0009] In this case, it is generally necessary to use an external sensor calibration method, that is, to regularly connect the tablet or flat-panel display to a separate external sensor for color and brightness measurement calibration. However, since the frequency of use of external devices is much lower than daily use, it is unlikely to be carried with you.

[0010] It can be seen that in order to solve the above technical problems, a display device including an optical sensor is urgently needed. Utility Model Content
