The power consumption of lcd monochrome LCD is usually related to 4 elements (without considering external components):

1. LCD Screen Size

Because the inside of the LCD is actually composed of lines, and the larger the size of the LCD, in addition to the content will be more, the key is that the distance between the lines will also become longer, so the larger the size, the greater the power consumption will certainly be.

2. LCD Screen Type

LCD will also be classified, usually customers can often hear the LCD low impedance, high impedance, the so-called low impedance and high impedance, refers to the LCD internal line resistance value, the lower the line resistance value of the natural loss of current is lower, power consumption is also relatively low.

3. Chip Type

Here the chip type actually has no direct relationship with the power consumption of the LCD, the chip is actually its load capacity, and many people who are not professional enough tend to ignore this, which leads to the design of the LCD screen bugs and hidden problems!

We design the LCD is to take into account the chip and glass matching, such as an LCD full load drive power consumption needs 100 microamps, while the maximum support capacity of the chip can only reach 80 microamps, the production of LCD once the need for a full screen display will appear no display, no scratches, contrast reduction and some other unexpected problems.

And the specifications of each chip will state its maximum supported operating current. Therefore, if you need to develop a new LCD screen, you must not ignore its matching problem.

4. Backlight

In fact, if we consider the power consumption, 99% of the power consumption of LCD is undoubtedly consumed by the backlight.

The power consumption of the backlight is easy to calculate, usually calculated by the number of LED beads in the backlight, a standard 15mA light power consumption, 3 lights is 45mA.

Before that, we also shared two technical articles on LCD display effects." LCD monochrome LCD positive display negative display difference" "LCD translucent, fully transparent, reflective difference", combined with what we have learned today about power consumption, in fact, it is easy to conclude that, in general, reflective LCD power consumption is the lowest, followed by translucent LCD, the highest power consumption is definitely fully transparent LCD, because in order to ensure the display effect, fully transparent LCD backlight number is usually the most.

So, after learning so much knowledge, I believe we have taken another step forward in the selection of LCD monitors. In the future, we at Sinda Display will share more knowledge about LCD monitors to help you understand.
