户外全彩LED显示屏的验收可以从哪些方面分析? What aspects can be analyzed for the acceptance of outdoor full-color LED d

一。颜色还原性是指显示屏对颜色的还原性,

One. Color reducibility refers to the reducibility of the display screen to the color,

即显示屏上显示的颜色应与回放源的颜色高度一致,

That is, the color displayed on the display should be highly consistent with that of the playback source,

以保证图像的真实性。

To ensure the authenticity of the image.

2。色块的存在与否是指相邻模块之间存在明显的色差。

2. The existence of color block refers to the obvious color difference between adjacent modules.

颜色转换基于模块。

Color conversion is based on modules.

色块现象主要是由于控制系统差、灰度低、扫描频率低造成的。

Color block phenomenon is mainly caused by poor control system, low gray level and low scanning frequency.

三、马赛克和死点现象马赛克是指显示屏上总是亮或经常黑的四个小方块,即模块坏死。

3. Mosaic and dead spot phenomenon mosaic refers to the four small squares that are always bright or often black on the display screen, that is, module necrosis.

主要原因是显示屏使用的接口质量不合格。

The main reason is that the interface quality of the display screen is unqualified.

死点是指LED显示屏上始终亮或始终黑的单个点。

Dead point is a single point that is always on or always black on the LED display.

死点的数量主要取决于管芯的质量。

The number of dead points mainly depends on the quality of the core.

四、平整度LED显示屏的表面平整度应在±1mm以内,以保证显示图像不失真,

IV. flatness the surface flatness of LED display shall be within ± 1mm to ensure that the display image is not distorted,

局部凸起或凹陷会造成显示屏视角死角。板形主要由生产工艺决定。

Local bulge or depression will cause dead angle of view angle of display screen. The shape of the plate is mainly determined by the production process.

五、亮度及视角:室内全彩屏幕亮度应大于800cd/m2,室外全彩屏幕亮度应大于7500cd/m2,以保证显示屏正常工作。

V. brightness and viewing angle: the brightness of indoor full-color screen shall be greater than 800cd / m2, and the brightness of outdoor full-color screen shall be greater than 7500cd / m2 to ensure the normal operation of display screen.

否则,由于亮度低,显示的图像可能看不清。亮度主要取决于LED灯芯的质量。

Otherwise, the displayed image may not be visible due to low brightness. The brightness mainly depends on the quality of LED core.

视角的大小直接决定了屏幕的观众数量,所以越大越好。

The size of the perspective directly determines the number of viewers on the screen, so the bigger the better.

视角的大小主要由管芯的包装方法决定。

The size of the viewing angle is mainly determined by the packing method of the tube core.

白平衡效应白平衡效应是显示屏最重要的指标之一。

White balance effect white balance effect is one of the most important indicators of display screen.

在色度学中,当红、绿、蓝三原色的比例为1:4.6:0.16时,显示纯白色。

In chromaticity, when the ratio of red, green and blue primary colors is 1:4.6:0.16, it shows pure white.

如果实际比例稍有偏差,就会出现白平衡偏差。

If there is a slight deviation in the actual proportion, there will be a white balance deviation.

一般来说,要注意白色是否有蓝偏和黄绿偏。

Generally speaking, we should pay attention to whether white has blue bias and yellow green bias.

白平衡的质量主要由显示屏的控制系统决定,而管芯对色彩恢复也有影响。

The quality of the white balance is mainly determined by the control system of the display screen, and the tube core also affects the color restoration.

虽然目前LED电子显示屏的需求已接近饱和,但随着新显示屏产品的开发,以及新需求市场和应用环境的突破,将给国内LED显示屏市场带来新的机遇。

Although the demand of LED electronic display screen is nearly saturated at present, with the development of new display screen products, as well as the breakthrough of new demand market and application environment, it will bring new opportunities to the domestic LED display screen market.

在有机的相遇中会有挑战。

There will be challenges in organic encounters.

随着行业竞争的加剧,未来LED显示屏市场将继续增长,但另一方面也将加大对部分中小LED显示屏厂商的改造或淘汰力度。

With the aggravation of industry competition, the LED display market will continue to grow in the future, but on the other hand, it will also increase the transformation or elimination of some small and medium led display manufacturers.
