全彩led显示屏怎么鉴定好坏? How to identify the quality of full-color LED display?

一。平整度。

One. Planeness.

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,局部凸起或凹陷会导致显示屏视角死角。

The surface flatness of LED display screen shall be within ± 1mm to ensure that the display image is not distorted, and local bulge or depression will cause dead angle of view angle of display screen.

板形主要由生产工艺决定。

The shape of the plate is mainly determined by the production process.

2。亮度和视角。

2. Brightness and viewing angle.

室内全彩屏幕的亮度应大于800cd/m2,室外全彩屏幕的亮度应大于1500cd/m2,以保证显示屏的正常工作,否则,由于亮度低,显示图像将看不清。

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 1500cd / m2 to ensure the normal operation of the display screen, otherwise, because of the low brightness, the displayed image will not be clear.

亮度主要由LED灯珠的质量决定。

The brightness is mainly determined by the quality of LED lamp beads.

视角的大小直接决定了LED显示屏的受众数量,所以越大越好。视角的大小主要由管芯的包装方法决定。

The size of perspective directly determines the number of audiences of LED display, so the larger the better. The size of the viewing angle is mainly determined by the packing method of the tube core.

三。白平衡效应。

Three. White balance effect.

白平衡效应是LED显示屏的重要指标之一。

White balance effect is one of the important indexes of LED display.

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LED显示屏的控制系统决定,而灯珠也会对色彩的还原产生影响。

The quality of white balance is mainly determined by the control system of LED display, and the lamp beads will also have an impact on the color restoration.

四。颜色还原性。

Four. Color reducibility.

色彩还原性是指LED显示屏对色彩的还原性。

Color reducibility refers to the reducibility of LED display to color.

LED显示屏上显示的颜色应与回放源的颜色高度一致,以保证图像的真实性。

The color displayed on the LED display shall be highly consistent with that of the playback source to ensure the authenticity of the image.

5个。产品设计。

5. Product design.

全彩LED显示屏种类繁多,室内外节能、高亮度、高刷新、便携等产品,

There are many kinds of full-color LED display, such as indoor and outdoor energy-saving, high brightness, high refresh, portable and other products,

各行各业对LED显示屏有不同的要求,

All walks of life have different requirements for LED display,

所以当买方区分LED显示屏的质量并选择LED显示屏时,

So when the buyer distinguishes the quality of LED display and selects LED display,

他们应该收集自己的需求,以及制造商的LED显示屏产品是否能够满足自己的需求。

They should collect their own needs and whether the manufacturer's LED display products can meet their own needs.

6。材料控制。

6. Material control.

材料的选择对LED显示屏的质量起着决定性的作用。

The choice of materials plays a decisive role in the quality of LED display.

选用优质原材料,从源头上控制LED显示屏的质量。

Select high quality raw materials to control the quality of LED display from the source.

所以作为买方检验的重点。

Therefore, it is the focus of the buyer's inspection.

1)高端LED灯代表Nichia Kerui(芯片封装)的中级水晶灯。

1) the high-end LED lamp represents the intermediate crystal lamp of Nichia Kerui (chip package).

LED灯具涉及到LED的中间产业链,尤其是国内的包装行业。

LED lamps and lanterns are related to the intermediate industrial chain of LED, especially the domestic packaging industry.

同样,由于包装厂家的不同,LED晶体光芯片的质量也不清楚。

Similarly, due to different packaging manufacturers, the quality of LED crystal light chip is not clear.

高端LED轻包装管的中高档产品代表Yiguang(台湾)Guoxing Lehman。

Yuguang (Taiwan) Guoxing Lehman is the middle and high-end product representative of high-end LED light packaging tube.

2)led驱动IC:吉吉科技作为世界领先的led驱动厂商,多年来一直在led显示驱动领域排名第一,

2) led driver IC: as the world's leading LED driver manufacturer, Jiji technology has been ranked first in the field of LED display driver for many years,

在中国led显示驱动领域的占有率已超过60%,

The share of LED display driver in China has exceeded 60%,

50%以上的全球市场份额积累5024是中高端led显示产品的首选。

More than 50% of the global market share of 5024 is the first choice of high-end LED display products.

3)电源底座(加强型):电源底座是连接电源线和PCB板的主要设备。

3) power base (reinforced): the power base is the main equipment connecting the power line and PCB board.

虽然不是决定LED显示屏质量的主要方面,

Although it is not the main aspect that determines the quality of LED display,

但其坚固的耐久性和导电性也影响着显示屏的使用寿命和防护水平。

But its strong durability and conductivity also affect the service life and protection level of the display screen.

4)排针(带简单喇叭):排针是控制系统和PCB控制电路的主要部件,通过排针连接。

4) needle arrangement (with simple horn): needle arrangement is the main part of control system and PCB control circuit, which is connected by needle arrangement.

优先采用带喇叭的排针方式,既可防止排针反插造成返工,

Priority should be given to needle arrangement with horn, which can not only prevent rework caused by reverse insertion of needle arrangement,

又可有效防止外露的针对筛网和维修人员的损坏。

It can also effectively prevent the exposed damage to the screen and maintenance personnel.

5)电阻、电容等元件:俗话说,没有太大或太小的。

5) resistance, capacitance and other components: as the saying goes, there is not too large or too small.

由于LED显示屏经常开关,电容的质量也会影响显示屏在开关时的保护。

Because LED display often switches, the quality of capacitance will also affect the protection of display when switching.

电阻是控制显示屏电流的主要元件,有首选的大型品牌产品。

Resistance is the main component to control the current of the display screen, and it has the first choice of large brand products.

6)led模组面罩及底壳:主要材料为塑料。

6) led module mask and bottom shell: the main material is plastic.

进口优质材料,抗变形,环保性强。

Imported high quality materials, anti deformation, strong environmental protection.
