How Infinity Reduces LED Display Power Consumption
In general, the power consumption of an LED display is primarily determined by its displayed luminance. It can be expressed as:
where P is the power consumption under displayed content, 
is the display’s baseline power consumption when no image is displayed, L is the average display luminance, and K is the coefficient relating luminance to power consumption.
Within the Infinity end-to-end solution, power consumption is reduced through two core technologies:
1.Adaptive brightness control in the control system
Dynamically reduces the effective K x L component by adapting display brightness to content and operating conditions.
2.Reduced static power consumption in the driver IC
Directly lower 
, thereby reducing the display’s baseline energy consumption.
Adaptive Brightness Control Technology in the Control System
The ABL (Auto Brightness Limit) algorithm within the dynamic booster analyzes and quantifies the brightness or gamma distribution of image content on a frame-by-frame basis. It then dynamically adjusts display brightness according to the proportion of high-brightness content.
When a frame contains a large high-brightness area, the system reduces overall brightness to lower power consumption. Conversely, for high-contrast content with only a limited proportion of high-brightness areas, the display is allowed to reach its peak brightness, preserving the intended contrast performance.
This dynamic brightness-control approach improves viewing comfort by preventing excessive brightness in predominantly bright scenes, while maintaining strong high-contrast image quality when required. It also further reduces overall power consumption.
Low-Power Consumption Technologies of TBS Driver IC
- Deep-sleep power reduction
When an LED display is in standby mode or presents a black screen for an extended period, driver ICs can lower as much as 60% of total display power consumption. Because the driver IC is not required to operate under these conditions, it can enter an ultra-low-power deep-sleep mode to reduce total system energy consumption. TBS-developed driver ICs consume only 15% of their normal operating power in deep-sleep mode.
When only one LED within an IC’s controlled area is illuminated, the channels corresponding to the remaining LEDs can enter a low-power mode. Compared with conventional ICs, this fine-grained channel-level power management enables lower energy consumption. In practical testing, it has achieved energy savings of more than 20% relative to conventional LED solutions. Combined with algorithmic innovations, it can also reduce temperature rise in LED displays.
Dynamic power-saving mode
During normal operation, if the display area driven by a particular IC is rendering black content, its display-driving function is unnecessary and can be disabled to reduce IC power consumption. Its communication interface must, however, remain active to receive display data from the control system and determine whether normal operation must resume in the next frame. The driver IC must therefore be able to enter and exit dynamic black-screen low-power mode on a frame-by-frame basis.
TBS driver ICs support this operating mode, consuming only 30% of their normal display power in dynamic power saving mode. When the display presents near-black content, total display power consumption can be reduced substantially—by up to 42%.
Dynamic pixel-level power-saving mode
LEDs do not remain continuously illuminated during image display; instead, they are switched on and off repeatedly at high frequency under driver-IC control. During LED off intervals, the associated drive circuitry can be disabled. In particular, when certain LEDs within a scanned row are not required to illuminate, their drive circuits can remain disabled throughout that scan interval.
TBS driver ICs support dynamic pixel-level power saving mode. Even when LEDs must be activated in every scan,the power consumption of driver IC can be reduced by up to 20%.
