顏色的復原性顏色的復原性是指顯現屏對顏色的復原性，既顯現屏顯現的顏色要與播映源的顏色保持高度一致，這么才可以確保圖畫的真實感。
Restoration of restoration of the color refers to the color of the screen showing recovery, both display shows the color to color and broadcast sources are consistent, so it can ensure the authenticity of the picture.
濟南標識制作主要能夠從以下六個方面來剖析：
Ji'nan logo production can be analyzed from the following six aspects:
一、顏色的復原性顏色的復原性是指顯現屏對顏色的復原性，既顯現屏顯現的顏色要與播映源的顏色保持高度一致，這么才干確保圖畫的真實感。
Recovery of color, color restoration refers to the restoration of color screen appeared, both display shows the color to color and broadcast sources are consistent, so to ensure the authenticity of the picture.
二、有無色塊色塊是指相鄰模組之間存在較顯著的色差，顏色的過渡以模塊為單位了，引起色塊景象主要是由控制系統較差，灰度等級不高，掃描頻率較低造成的。
Two, there is no color color refers to the color difference is significant between adjacent modules, color transition in modular units, caused mainly by the color vision control system is poor, gray level is not high, resulting in lower scanning frequency.
三、有無馬賽克、死點景象馬賽克是指顯現屏上呈現的常亮或常黑的小四方塊，既模組壞死景象，其主要原由于顯現屏所選用的接插件質量不過關。死點是指LED顯現屏上呈現的常亮或常黑的單個點，死點的多少主要由管芯的好壞來決議。
Three, there is no mosaic, mosaic dead scene appears on the screen is often bright or black box is often small, necrosis of the primary module scene, because the screen selected connector quality. The dead point refers to the LED single point appears on the screen appear often bright or often black, the number of dead is mainly composed of the tube core is good resolution.
四、平整度LED顯現屏的表面平整度要在±1mm以內，以確保顯現圖畫不發生歪曲，部分凸起或凹進會致使顯現屏的可視視點呈現死角。平整度的好壞主要由生產工藝決議。
Four, the flatness of the surface of the LED display screen to be less than + 1mm, to ensure that the picture does not appear distorted, part of the convex or concave will cause the visual angle of the display screen showing dead. Flatness is mainly determined by the production process.
五、亮度及可視視點室內全彩屏的亮度要在800cd/m2以上，室外全彩屏的亮度要在1500cd/m2以上，才干確保顯現屏的正常作業，否則會由于亮度太低而看不清所顯現的圖畫。亮度的巨細主要由LED管芯的好壞決議。可視視點的巨細直接決議的顯現屏受眾的多少，故而越大越好。可視視點的巨細主要由管芯的封裝方法來決議。
Five, brightness brightness and visual view indoor full color to above 800cd/m2, the brightness of outdoor full color in 1500cd/m2 above, in order to ensure the normal operation of the screen appears, otherwise it will be because the brightness is too low and can not see the picture show. The brightness of the size of tube core is mainly composed of LED resolution. How much direct resolution display visual point of view of the size of the audience, so better. The size of the main visual view is determined by the tube core encapsulation method.
六、白平衡作用白平衡作用是濟南標識制作最重要的目標之一。顏色學受騙紅綠藍三原色的份額為1:4.6:0.16時才會顯現出純粹的白色，如果實踐份額有一點誤差則會呈現白平衡的誤差，通常要注意白色是不是有偏藍色，偏黃綠色景象。白平衡的好壞主要由顯現屏的控制系統來決議，管芯對顏色的復原性也有影響。
Six, the white balance of the role of white balance is one of the most important target of Ji'nan logo. Color had three primary colors share 1:4.6:0.16 will show the pure white, share a little error if the practice error appears white balance, usually pay attention to the white is not biased blue, yellow green scene. The quality of white balance is mainly determined by the control system of the display screen, and the core has an effect on the restoration of color.
