Embodiment

[0047] Reference as Figure 1-3 As shown, in this embodiment, the system storage unit also stores the recommended range of display operating temperature; when the display operating temperature monitored by the temperature sensor is within the recommended operating temperature range of the display, the display control unit controls the display to work at the first Target brightness value.

[0048] The system also includes an alarm module; the storage unit also stores a display operating temperature warning value. When the display operating temperature monitored by the temperature sensor exceeds the display operating temperature warning value, the display control unit turns off the backlight light source through the backlight drive unit, and at the same time passes the alarm module. Send an alarm signal. Obviously, the display operating temperature warning value is higher than the display operating temperature threshold, which can be set according to the attenuation characteris...

Abstract

The invention discloses a method and a system for realizing brightness continuous consistency of a display device. The method comprises the following steps of setting a to-be-selected brightness target value and a working temperature threshold value of the display device before delivering out of a factory; calibrating the brightness of a liquid crystal panel within the temperature threshold value, so as to obtain the corresponding relationship of the backlight target value and the brightness target value. The method has the advantages that after delivering out of factory, when the display device works within the working temperature threshold value, the brightness continuous consistency of the display device is maintained through the real-time monitoring and adjusting of backlight; when the working temperature of the display device exceeds the threshold value, the brightness continuous consistency of the display device is maintained through the real-time monitoring and adjusting of the temperature, and the switching of target brightness of the display device; the brightness continuous consistency of the display device is guaranteed in the whole life cycle, and the significant meaning is realized for fields with higher brightness consistency requirements, such as medical field.

Description

technical field [0001] The invention relates to the technical field of display control of a display, in particular to a method and a system for realizing continuous brightness consistency of a display. Background technique [0002] Brightness consistency is of great significance for professional displays. However, after using a traditional display for a period of time, due to the attenuation of the brightness of the LCD panel itself, there is an obvious difference between the brightness and the target brightness set by the factory. This can also be intuitively observed by comparing the old and new displays. The backlight stabilization mechanism of traditional displays does not consider the influence of temperature on the backlight, and setting the backlight target value without considering the temperature factor is risky. When the operating temperature of the display changes, when the backlight value is adjusted to the backlight target value, the brightness of the display d...
