Description

一种LED显示系统及其控制方法 An LED display system and a control method

技术领域 FIELD

[0001]本发明涉及LED显示技术领域,具体涉及一种LED显示系统及其控制方法。 [0001] The present invention relates to the field of LED display technology, particularly relates to an LED display system and a control method.

背景技术 Background technique

[0002]大屏幕LED显示屏具有亮度高、使用寿命长、大视角范围、色彩丰富以及对室内外环境适应能力强等优点,目前已成为最具优势的新一代广告宣传和信息传播的载体,广泛应用于体育场馆、道路交通、金融证券交易、广告传媒等信息显示领域。 [0002] large-screen LED display with high brightness, long life, large viewing angle range, rich color and intensity of indoor and outdoor environmental adaptability, etc., has become the most advantage of the new generation of carrier advertising and information dissemination, widely used in the field of information display stadiums, road traffic, finance and securities transactions, advertising and other media. 但实际使用中由于环境光的变化,会影响到LED显示屏,尤其是户外屏或半户外屏的显示效果。 However, in actual use due to changes in ambient light, the LED display will affect, in particular for outdoor display or screen semi-outdoor screen. 所以,当环境光线较亮时需要提高LED显示屏的亮度,反之环境光线变暗时,则需要降低LED显示屏的亮度,这样才会有更好的视觉效果。 Therefore, when ambient light is bright LED display brightness necessary to increase, whereas when the ambient light dims, you need to reduce the brightness of the LED display, this will have a better visual effect. 但是,增加LED显示屏的亮度会使得屏体发热增加,造成屏体温度升高。 However, increasing the brightness of the LED display screen body such that heat increases, resulting screen body temperature. 尤其是在阳光强烈的户外环境中本来环境温度就较高,两种因素共同作用下会导致屏体温度异常升高而影响其正常工作,甚至会影响LED显示屏的安全。 In particular it would have a higher ambient temperature in strong sunlight outdoor environment, both factors together can cause abnormal screen body temperature rises affecting its normal work, and even affect the safety of the LED display.

[0003]目前有一种技术能够通过温度传感器实时检测LED显示屏的温度值,当温度值超过危险值后会自动关闭LED显示屏。 [0003] Currently there is a technique capable of detecting the temperature of the LED display in real time by the temperature sensor, when the temperature exceeds a dangerous level will automatically turn off LED display. 这种技术虽然能够确保LED显示屏的安全,但是若不能有效降低LED显示屏的温度,可能会影响LED显示屏工作的连续性,而导致客户不满。 Although this technique can ensure the safety of the LED display, but if it can not effectively reduce the temperature of the LED display, LED display may affect the continuity of the work, which led to customer dissatisfaction.

[0004]最新的技术中,LED显示屏内设置了一个或者数个散热风扇来强制散热。 [0004] In the latest technology, the LED display is provided with a plurality of cooling fans or by forced cooling. 但是目前的技术只能在屏体温度升高到一定值后开启风扇,低于一定值后关闭风扇,或者在屏体工作时一直开启风扇,而不能根据需要进行调整。 However, the current technology only in the screen body temperature rises to a certain value the fan is turned on, the fan is closed below a certain value, or when the fan has been turned on screen body work and can not be adjusted as needed. 因而此种方式使LED显示屏增大了不必要的功耗,与当今环保节能的趋势相违背。 Thus in this way the LED display increases unnecessary power consumption, and contrary to the current trend of energy saving and environmental protection.

[0005]综上所述,在确保LED显示屏安全的前提下,目前还没有一种技术能够很好的解决当环境温度变化时LED显示系统在显示效果和环保节能两方面求得平衡的问题。 [0005] In summary, in the LED display to ensure the safety of the premise, there is no technology can be a good solution when the ambient temperature changes LED display system obtained in both display and environmentally friendly energy balance problems .
