IPS lcd is better in contrast than TN TFT LCD:
IPS LCD is better than tft lcd in contrast, what is the reason? Because as we mentioned on the upper, IPS LCD is negative display mode, and the light can not transmit it when power off, it would be more black when in display off, IPS LCD is more easily to get the high contrast because it have more blacker background when in power off. Because the high contrast on IPS display, so IPS lcd can be more brilliant color image – this is a huge advance in technology than a Twisted Nematic (TN) display.
Which is better for power saving : IPS vs TFT LCD
TN TFT screen has more than around 20% power consumption than IPS tft. The reason from the array way of liquid crystal inside the IPS LCD. since the liquid crystal materials are arrayed in the plane, the power would be save for switching on liquid crystal in IPS than twist it in tft lcd, that is the reason IPS screen is better than TN lcd in power consumption.
Concerning the IPS tft have better contrast, but in the same time, it have smaller transmissive ratio, so we need more light from lcd backlight, if used more led chips, so it also need more power to the lcd backlight, so the total display module might need more power consumption if the backlight driving current for IPS LCD. so we need to more concern about the backlight current consumption instead of the IPS lcd lcd screen itself. The main power consumption would be from the lcd backlight, not the lcd screen.
Transflective TFT-LCD modules have both “transmissive” and “reflective” modes.
Both display modes work together for enhanced performance.
In darker environments, the “transmissive” mode is dominant with emissions from the display’s backlight.
In daylight or bright environments, the “reflective” mode of the display is more dominant through reflectance from the internal mirror structure.
Transflective TFT display screen have a layer of reflector in front of the backlight. The incoming light is reflected on the reflector layer and used to illuminate the TFT display. as the transfelctive screen, Transflective TFT LCD display modules have both "transmissive" and "reflective" characters.
Transflective displays tft are characterized by well readability in bright ambient light and direct sunlight. While transmissive TFT lcd displays can only be operated with a backlight, transflective screen feature the reflector on the color filter of TFT cell, thatin Therefore, its incoming ambient light is reflected on the TFT reflective layer and reflect to illuminate the display. As a result, the readability of the content in very bright sun light is perfect even without backlight.
Advantage of transflective screen:
Another advantage of transflective display TFT modules is power savings compared to traditional “transmissive- only” displays. transflective lcd display combines the advantages of transmissive and transflective lcd displays, we also call it transreflective screen, the transflective screen are perfectly readable under almost any ambient light conditions. In addition, they are very energy efficient, making them ideal for battery powered devices and mobile applications.Customers using a transflective screen can save power by reducing or turning off the display’s backlight during bright environments because the “reflective” mode is dominant.
半透反射式tft显示器的反射率较低，与室内应用的透射式显示器相比，导致日光下的显示颜色和效果不够好，但如果在透射模式下选择高亮度的tft显示器，则显示效果会更好半透半反式tft显示器的最先进之处在于省电，如果在手持设备中使用半透半反式tft显示器，例如室外的手持GPS，半透半反式tft显示器将是一种节能的方式。但是，如果要在户外的公共显示器（例如广告牌，售货亭）中，透反射式tft的显示效果将无法对这些公共显示器具有良好的显示效果，对于这些应用而言，高可见光的透射式tft显示器对于日光可见是更好的选择。
