Description
Technical field
The present invention relates to a kind of device and method of demonstration, relate in particular to a kind of device and method that shows low-light level.
Background technology
The super brightness of display panels under complete white picture can reach more than the 1000nits at present, as adjusting the drive integrated circult plate with current/voltage, then can reach 10nits at the minimum brightness under the complete white picture, at this moment, brightness ratio higher (the brightness ratio value defined is the display panel maximum brightness that can present and the ratio of minimum brightness).But under this kind situation, will be because of the too small operating voltage that circuit board can't be provided of electric current, thus cause picture scintillation to occur or dark picture directly occurs.
For making display panels have high brightness than above-mentioned scintillation not occurring, the dealer has proposed a kind of ultralow brightness device shown of finishing under the situation that does not spend hardware cost.
Summary of the invention
In view of the above problems, the invention provides a kind of device and method of low-light level demonstration, it does not spend hardware cost can reach the night vision demand.
For this reason, the present invention has adopted following technical scheme: a kind of device of low-light level demonstration, and it comprises that mainly one starts module, in order to start an operating system; One microprocessor, it receives the brightness adjustment instruction that the user sends, and judges the brightness show state of current operation system; One signal correction module, its brightness show state according to operating system is revised the brightness of operating system, and exports a setting signal, and wherein above-mentioned setting signal comprises a standard setting signal and a low-light level setting signal; And a display module, receive and according to above-mentioned setting signal display standard luminance patterns or show low-luminance mode.
Preferable, the invention provides a kind of device of low-light level demonstration, wherein, described microprocessor mainly comprises a receiving element and a judging unit, the brightness adjustment instruction that described receiving element sends in order to receive the user, and judging unit is in order to judge the brightness show state of current operation system.
Preferable, the invention provides a kind of device of low-light level demonstration, wherein, described display module is a LCD display curtain or a CRT display screen.
The present invention also provides a kind of method of low-light level demonstration, it is characterized in that, this method mainly may further comprise the steps:
Start an operating system; Receive the brightness adjustment instruction that the user sends, and judge the brightness show state of current operation system; Brightness show state according to operating system judges whether the brightness of operating system is revised, and exports a setting signal, and wherein above-mentioned setting signal comprises a standard setting signal and a low-light level setting signal; And receive the setting signal and the display standard luminance patterns of above-mentioned output or show low-luminance mode.
Preferable, the invention provides a kind of method of low-light level demonstration, wherein, if when the brightness show state of current operation system is the standard setting signal, then the brightness of established standards and not to operating system brightness revise; And when if the brightness show state of current operation system is the low-light level setting signal, then set low-light level and to operating system brightness revise.
Compared to prior art, the invention provides a kind of device and method of low-light level demonstration, by revising operating system brightness, will repair to target brightness value under the system brightness value, thereby show the low-light level display mode, do not spend hardware cost and reach the night vision demand.
