How can I make the colour display of the led display more vibrant?

Colour in the led display visual effect occupies a very important position, but also when we buy to discern the quality of one of the criteria for good or bad product quality. In the production of led display chromaticity uniformity has always been the focus of manufacturers breakthrough, the general public believe that LED brightness unevenness can be improved by single-point correction, while chromaticity unevenness can not be corrected, can only be improved by subdivision and screening of LED colour coordinates. How can we make the colour display of led displays more vibrant?

Manufacturing led displays, firstly according to the luminance index to choose the optional light emitting or display module, secondly according to the selected product red, green, blue colour intensity to determine the colour as a basis, usually low luminance ratio as a luminance reference, when the baseline maximum luminance adjustment, another (bi-colour) or 2 (full colour). For bi-colour displays, large in most cases, green is used as the base and the operating current of the red 2 transistors is adjusted.

Generally lower the operating current to balance the yellow colour, adjust the standard, such as reducing the brightness of the entire display screen. led display colour adjustment to the optimum state of balance, will make the screen brightness reduced. If the display screen to achieve the brightness requirements, will each colour to reach the maximum brightness, and then lose balance. For example: dual colour screens yellow or red and green.

We found that even the first international brands with leading also have a greater wavelength deviation in colour saturation and bias, and the deviation range greatly exceeds the human eye for green colour difference difference threshold, therefore, the chromaticity uniformity correction is important. Luminous colours and luminous efficiency and luminous materials and production processes are now widely used in the three primary colours of red, green and blue. As light-emitting diodes display low operating voltage, can be active light and have a certain brightness, brightness and voltage (or current) regulation, shock resistance, resistance to vibration itself, long life, so in large display devices.

LED light-emitting materials applied to led displays are available in the following forms:
1, light emitting diode dot matrix module composed of a diverse array of wafers forming a luminous moment array, using epoxy resin sealed in a plastic shell. Fitted line column scanning drive, easy to form a high-density display for indoor displays.
2, SMD light-emitting diode lamp (or light-emitting diode) of is a light-emitting lamp welding form of packaging, can be used indoor led display, can achieve a single point of maintenance, effectively overcome the mosaic phenomenon.
3, light-emitting lamp consists of a light-emitting diode chip, reflective bowl metal anode, cathode, metal structure, the epoxy resin shell of the outer package light gathering capacity. Supplied in one or more (different colours) to form a single light basic pixel, due to the high brightness, for outdoor led display.
