Problems solved by technology

In the traditional brightness stabilization mechanism, only the brightness of the highest gear is corrected, and the brightness of other gears is obtained through calculation. This scheme is difficult to ensure that the brightness of each gear meets the set value, and it is impossible to realize the display brightness of multiple monitors at the same brightness gear. consistency

Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0013] The present invention provides a specific embodiment of a working method of a real-time multi-stage brightness stabilization system. In this embodiment, the brightness adjustment is divided into 5 gears, and the brightness values ​​of each gear are respectively a, b, c, d, e. The steps are as follows:

[0014] Step 1: Reference figure 1 As shown, a brightness stabilization system is established: a backlight sensor is installed in the display, and the backlight sensor obtains the return value of the display backlight in real time. There is a corresponding relationship between the return value and the actual display brightness of the display, and each actual display brightness corresponds to a backlight sensor target return value. For a specific brightness, compare the real-time return value of the backlight sensor with the target return value of the ...

Abstract

The invention discloses a working method of a real-time multi-order brightness stabilization system. The working method comprises a brightness stabilization step and an order-by-order brightness calibration step. According to the working method provided by the invention, the brightness of each order of medical displays is calibrated, together with a liquid crystal display backlight stabilization system, the bright consistency and stability of the displays are ensured and the diagnosis correctness and efficiency of the doctors are improved.

Description

technical field [0001] The invention relates to a working method of a real-time multi-stage brightness stabilization system. Background technique [0002] Brightness stability is an important index to evaluate the image display quality of medical monitors. The backlight of the monitor will age with the use of time, which will cause the attenuation of the brightness of the image display. Establishing a brightness stabilization mechanism can effectively ensure the stability of the brightness of the monitor. In the traditional brightness stabilization mechanism, only the brightness of the highest gear is corrected, and the brightness of other gears is obtained through calculation. This scheme is difficult to ensure that the brightness of each gear meets the set value, and it is impossible to realize the display brightness of multiple monitors at the same brightness gear. consistency. When using multiple monitors for comparative diagnosis, brightness consistency is a necessary ...
