### 7.7.4 Estimating the Long-Term Average Landed Duty Cycle of a Product or Application

During a given period of time, the Landed Duty Cycle of a given pixel follows from the image content being displayed by that pixel.

For example, in binary pattern display with value '1' or when displaying pure-white on a given pixel for a given time period, that pixel will experience a 100/0 Landed Duty Cycle during that time period. Likewise, a binary pattern display with value '0' or when displaying pure-black, the pixel will experience a 0/100 Landed Duty Cycle.

Table 7-1 Binary Pattern Mode Example: Binary Value and Landed Duty Cycle
BINARY VALUE NOMINAL LANDED DUTY CYCLE
0 0/100
1 100/0

During a given period of time, the landed duty cycle of a given pixel can be calculated as follows:

Equation 4. Landed Duty Cycle = ∑{Pattern[i]_Binary_Value} / {Total_Patterns}

where

• Pattern[i]_Binary_Value represent a pixel's pattern and its corresponding binary value over all patterns in the pattern sequence: Total_Patterns.

For example, assume a pattern sequence with three patterns using pixel x. In this sequence the first pattern has pixel x on, the second pattern has pixel x off, and the third pattern has pixel x off. Thus, the Landed Duty Cycle is 33%.
