LCD lighting methods include: transmissive, reflective, and transflective.
Compared to emissive display technologies such as OLED displays (organic light-emitting diodes) and VFDs (vacuum fluorescent displays), LCDs require a light source such as sunlight, artificial room light, or an integrated backlight, which is typically made of LED (light-emitting diode) semiconductors . Therefore, in the application of different products, different lighting modes need to be customized according to different scenarios. LCD lighting methods include: transmissive, reflective, and transflective.
How to understand transmissive, reflective, transflective, and the differences between them?
The following summarizes the definitions, advantages and disadvantages of the three.
Type | Definition | Advantage | Shortcoming |
Transmissive | Light from the backlight passes through the LCD glass, making the display brighter | Display content is very bright | The backlight also needs to be turned on at all times, as the display easily heats up and consumes high power. |
Reflective | Ambient light passes through the LCD unit from the front and is reflected back to the viewer by the mirror | Low power consumption and excellent visibility in direct sunlight | Not visible at night or in dark environments |
Transflective | Both transmissive and reflective, with an integrated backlight unit and a translucent reflector or a reflector with a hole per pixel | The display is clearly visible in direct sunlight, reduces power consumption in bright environments, and enables readability in any lighting condition | The price is slightly higher |
It can be seen from the table that the transflective display screen takes into account the advantages of the transmissive and reflective displays and is the best solution for display visibility.
Hot Display Technology is a display manufacturing expert with a senior team of technical engineers. Recently, we have developed this semi-transparent and semi-reflective TFT, which is suitable for the application of different products in different scenarios.
As shown below, the display effect of this semi-transparent and semi-reflective TFT is displayed outdoors in strong light and indoors with weak sunlight. It can be seen that the stronger the sunlight, the higher the brightness of the display. Of course, when the light is slightly weaker, When indoors, the display content is still clearly visible, and because this display is also equipped with a backlight, when it is in a dark environment, the backlight of the display will be turned on without affecting the operation of the display at all.
It can be seen that the semi-transparent and semi-reflective display screen is very flexible in application and has a wide range of application scenarios, especially suitable for some outdoor equipment.
The following Hot Display semi-transparent and semi-reflective TFT products are available for reference.
