Problems solved by technology

In medical diagnosis, diagnostic doctors often need to repeatedly read static medical images, which is also very easy to cause residual image problems on medical displays
At the same time, once the afterimage problem occurs on the medical display, it will also affect the doctor's image diagnosis, and even misdiagnose

Embodiment Construction

[0043] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0044]At present, when the LCD monitor displays the same picture for a long time and then switches the picture to the next new picture, the original picture will remain in the next new picture. This phenomenon is called Image Sticking. figure 1 Shown is the afterimage after the black and white checkerboard screen is switched to other grayscale full screens, also known as afterimage. As the LCD monitors are used longer and longer, the afterimage phenomenon will become more and more serious.

[0045] There are generally two reasons for image sticking. One is the phenomenon that the liquid crystal molecules are abnormally deflected to form a light leakage area due to the...

Abstract

The invention aims at the problem of afterimages of the traditional medical display in the aspect of static image display and the insufficiency in lacking of self-maintenance and maintenance measures for the display to provide a device and a method for afterimage elimination and self-maintenance of a medical display so as to eliminate the afterimages of the medical display and carry out self-maintenance for the medical display regularly. The value of the invention is to provide a practical and feasible solution for eliminating and preventing the afterimages of the medical display, and carrying out the self-maintenance for the medical display, thereby improving the picture display quality of the medical display, prolonging the service life of the medical display and helping a doctor to improve the diagnosis efficiency and accuracy on patient lesions.

Description

technical field [0001] The invention relates to the field of medical professional display, in particular, it implements a device and method for eliminating residual image of medical display and self-maintaining. Background technique [0002] In recent years, liquid crystal displays (LCDs) have been rapidly popularized due to their advantages of low operating voltage, low power consumption, low radiation, low space occupation, thinness and beauty, and have become the mainstream. Different from ordinary civilian displays, medical professional displays not only have extremely high requirements on technical parameters such as brightness, grayscale, and resolution, but also have extremely strict requirements on the image quality of the entire medical display, such as uniformity and afterimage. This is because any small difference in the image quality of medical images is of vital significance to the diagnosis, discovery and prevention of early lesions. [0003] Among them, after...
