For example, the 2.7 -inch display requires 80mA current to render all-white images, but only 5mA current display other icons or graphics. Therefore , OLED power supply required to achieve high conversion efficiency for all load currents . In order to achieve such OLEDModule efficiency , energy saving mode requires the use of advanced technology to reduce the load current to reduce the converter switching frequency. Since this is a voltage controlled oscillator through (VCO) is completed , it can be possible to minimize EMI problems , and can control the minimum switching Graphic LCD Module frequency outside the normal range of 40kHz audio , which may prevent the ceramic capacitor noise input or output . When using such devices in mobile phone applications, which is particularly important, and simplify the design process.
By emission characteristics for maximum power consumption is not white , is the brightness value to determine power consumption . Such as red , blue, green, white luminance value is generated when the light intensity values 30 10 together . So the red , green and blue values into a white value ( theoretical value ) 3.3 synthesized a 10. LED or OLED speaking from the human eye to see the same brightness , blue CFL .
OLED Module technology and development with echoes, OLED drive also plays an increasingly important role. Not only from the low duty cycle increases to support high duty cycle, and the application of such a control current for each RGB, wider IC operating temperature (-45 to 80 ℃), the internal DC-DC boost, as well as graphics acceleration instruction and some other features.
