A box cover is arranged above a control box; light-transmitting glass is arranged above the boxcover; a power switch is arranged above the box cover; an adjusting knob is arranged at one side of the power switch; an LCD screen is arranged below the box cover; a circuit board is arranged below the LCD screen; a wiring hole is arranged below the circuit board; heat dissipation slots are arranged at the two sides of the circuit board; and cooling fans are arranged inside the heat dissipation slots.
Description
technical field [0001] 本发明涉及屏幕亮度技术领域,具体为一种屏幕亮度控制装置。 Background technique [0002] A screen, also called a display screen, is an electrical appliance used to display images and colors. 屏幕亮度是指发光物体表面发光强弱的物理量称为亮度,物理学上用L表示,单位为坎德拉每平方米或称尼特。 亮度是衡量显示器屏幕发光强度的重要指标,对于显示器面板来说,高亮度也意味着对其工作环境的抗干扰能力更高。 人们在看屏幕时,都希望亮度越高越好,这样画面更艳丽,细节表现更出色,但是过分追求亮度不但使耗电量增加,更容易引发眼睛疲劳,出现眼涩、眼皮沉重等症状,甚至导致视力下降和头痛等健康问题。 如何控制屏幕亮度这个问题越来越重要。 [0003] 目前,屏幕的亮度控制大多都是提高光线传感器来直接调节,他会对某个界限,当光线强度高于或低于这个界限时,就会对屏幕的亮度进行自我调节,可是在对一些视力不佳或色弱的使用者进行图像演示时,就会出现亮度过高引发眼睛疲劳或亮度过低图像观察不清晰,不能满足使用需求。因此市场上急需一种屏幕亮度控制装置来解决这人些问题。 Contents of the invention [0004] 本发明的目的在于提供一种屏幕亮度控制装置,以解决上述背景技术中提出屏幕亮度自我调节在对视力不佳或色弱的使用者使用时会带来不便,不能满足使用需求的问题。 [0005] 为实现上述目的,本发明提供如下技术方案:一种屏幕亮度控制装置,包括控制箱,所述控制箱的上方设置有箱盖,且箱盖与控制箱之间通过螺钉连接,所述箱盖的上方设置有透光玻璃,且透光玻璃的一端贯穿箱盖并延伸至箱盖的下方,所述箱盖的上方设置有电源开关,所述电源开关的一侧设置有调节旋钮,且电源开关和调节旋钮的一端均延伸至箱盖的内部,所述箱盖的下方设置有LCD屏幕,且LCD屏幕与控制箱的内壁贴合连接,所述LCD屏幕的下方设置有电路板,且电路板与控制箱通过螺钉连接,所述电路板的下方设置有接线孔,且接线孔的一端贯穿控制箱并延伸至控制箱的外部,所述电路板的两侧均设置有散热槽,且散热槽的一端贯穿控制箱并延伸至控制箱的外部,所述散...
