Corning helped advance the TV industry from the cathode ray tube to LCD glass, and we look to the future with quantum dots, MiniLED, and MicroLED technology.

It is recommended to have at least 25 subgroups and preferably each subgroup having >1 data point. The greater the subgroups size the higher likelihood the special cause variation is detected and that it exist if it is detected.

Cpk process capability indexformula

A Cpk of 2.0 corresponds to approximately 6 sigma (short term) performance or 4.5 sigma (long term) if applying the shift.

Cpk and Cp are the two most commonly used capability indices in statistics. This is a video that we recommended to help grasp the similarities, differences, application, and calculations.

With a normally distributed set of data an approximation of Z from Cpk and vice versa can be made in substituting and solving within these two formulas.What is the Cpk approximated from a 6 sigma performance?Substituting the Z formula in Cpk (USL) and plugging in 6 for Z from the given data gives:

As with all the process capability indices, the process must be in control before assessing capability. This goes for the baseline measurement and the final measurement. Use time-series charts and SPC charts to determine process control. If the process is out of control (i.e. still rising with upward trend), then assessing the current process is unlikely to reflect the long term performance.

These Six Sigma Training modules provides lessons within Statistical Capability studies and much more. Understanding the basic meaning and applications for capability studies is necessary for any level of a Six Sigma Project Manager.

and since the maximum value for k is 1.0, then the value for Cpk is always equal to or less than Cp.Cpk will never exceed the Cp

Cpk is an option (along with z-score and PPM or DPMO) when describing process baseline measurement in the MEASURE phase. After the MSA is complete, the Six Sigma project has a goal of improving the baseline measurement. In order to measure improvement (or lack of) there must be a starting point. This is called the baseline measurement.

Process capability indexformula

The Cp is the best a process can perform if that process is centered on the midpoint. The Cp is commonly referred to as the process entitlement because, when centered, it represents the best performance possible.

A Cpk of 2.0 would represent a sigma = 6 which also means there are 3.4 DPMO created by the process in the "short term" which is the performance goal for a Six Sigma project. Read more about the process capability indices, their meanings, and relationships.

Essential to the process is a high-performance display glass – specifically, Corning Lotus™ NXT Glass. This glass acts as a carrier substrate for a thin layer of plastic, or polyimide. That’s the material that is ultimately molded, curved, or folded to form the display panel.

Therefore, it isn't possible to convert DPMO (or PPM) to an exact Cpk value unless you know how many DPMO are above the USL and below the LSL.

Remember Cpk takes into account the centering of the distribution of data among the USL and LSL. If the process is centered (k=0) then the defects are equally distributed on both tails. This is the same as converting DPMO to Cp.

Cpkformula

Think about it this way, if a subgroup size is 5 and all five data points show an average that is vastly different from the averages of the other subgroups (that also have 5 data points) then there is a strong chance that the subgroup was measured under a "unique" or special condition.

Once the glass substrate carries the polyimide-based panel to fruition, a UV laser helps cleanly separate it from the carrier glass substrate. The flexible polyimide-based panel, now functionally complete, can be bent and molded into today’s stylish smartphones and into the curved displays of the future.

Recall that the specification limits are set by the customer or your company. You may have only the USL and/or the LSL depending on your situation.

Flexible OLED devices are stunning in their brightness and resolution, but also in their form factors, delivering an immersive display experience along with sleek device designs.

Cpk is a short term process index that numerically describes the "within subgroup" or "potential" capability (Ppk is a long term indicator) of a process assuming it was analyzed and stays "in control". Cpk is one commonly applied metric to measure how a process (aka Voice of the Process VOP) is performing relative to the customer specifications (i.e. LSL, USL, target - Voice of the Customer (VOC)).

Because of its incredible ability to remain stable even under extreme heat, Lotus NXT Glass is the ideal carrier glass substrate for this process. It provides a solid foundation for the building of the polyimide backplane, ensuring it will remain stable as it transforms into a high-resolution panel.

The higher the Cpk, the lower the variation in the process.Similar to Ppk, the Cpk capability index is only a function of the standard deviation and mean of the data, not a nominal (target) value that may be historical or provided by the customer. The Cpm capability calculation accounts for a nominal value.Cpk also requires input from the customer for the lower specification limit (LSL) and upper specification limit (USL).There are two calculations from the formula providing two values for Cpk. Select the MINIMUM value as the Cpk and to serve as the baseline value. This minimum value must be equal to or greater than the minimum acceptability level.Unlike Cp (and Pp), the Cpk (and Ppk) index can be calculated using unilateral or bilateral tolerances. If only one specification is provided (unilateral) the use the value that involves that specification limit.In such case, there will not be a minimum (or maximum), just calculate using the formula that has a specification and use it for the Cpk value.

But before those exhilarating experiences can even begin, the flexible OLED panel must undergo a highly demanding, extremely high-temperature manufacturing process. This means, of course, that all materials used in the display must be structurally and thermally stable. Dimensions must not vary by the tiniest degree, even under temperatures beyond 500 degrees Celsius.

The addition of "k" in Cpk quantifies the amount of which a distribution is centered, in other words it accounts for shifting. A perfectly centered process where the mean is the same as the midpoint will have a "k" value of 0.The minimum value of "k" is 0 and the maximum is 1.0. A perfectly centered process will have Cp = Cpk.Both Cpk and Ppk relate the standard deviation and centering of the process about the midpoint to the allowable tolerance specifications.An estimate for Cpk = Cp(1-k).
