Abstract
Official abstract text for this publication.
Systems and methods for adjusting a brightness of a display panel by periodically measuring at least one physical property in at least one area of a display panel, generating measurement data, and adjusting the brightness of the display panel with use of the measurement data. The brightness can be adjusted to control temperature and aging, in response to measurements of physical properties measured in at least one area of the display panel.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of adjusting a brightness of an emissive display system: periodically measuring at least one physical property in at least one area of a display panel generating measurement data; and adjusting the brightness of the display panel with use of the measurement data. 2 . The method of claim 1 , wherein the measurement data comprises measurements of each at least one physical property, the method further comprising: comparing each measurement of each at least one physical property with at least one threshold generating a respective at least one comparison, wherein adjusting the brightness of the display panel is performed with use of the at least one comparison. 3 . The method of claim 1 further comprising: predicting the future state of at least one physical property with use of the measurement data generating at least one predicted physical property value; and comparing the at least one predicted physical property value with at least one threshold generating a respective at least one comparison, wherein adjusting the brightness of the display panel is performed with use of the at least one comparison. 4 . The method of claim 2 , wherein adjusting the brightness of the display panel comprises determining a target brightness for the display panel with use of the measurement data, wherein the target brightness falls within at least one acceptable range of brightness. 5 . The method of claim 3 , wherein adjusting the brightness of the display panel comprises determining a target brightness for the display panel with use of the measurement data, wherein the target brightness falls within at least one acceptable range of brightness. 6 . The method of claim 4 , wherein the at least one physical property comprises a rate of temperature change and the at least one threshold comprises a first threshold rate of temperature change and a second threshold rate of temperature change, wherein adjusting the brightness of the display panel comprises: determining the target brightness to be lower than a current brightness when the at least one comparison indicates that the rate of temperature change is greater than the first threshold rate of temperature change and when the current brightness is greater than a minimum acceptable brightness of said at least one acceptable range of brightness; and determining the target brightness to be higher than the current brightness when the at least one comparison indicates that the rate of temperature change is less than the second threshold rate of temperature change, and when the current brightness is less than a maximum acceptable brightness of said at least one acceptable range of brightness. 7 . The method of claim 4 , wherein the least one physical property comprises a temperature and the at least one threshold comprises a first threshold temperature and a second threshold temperature, wherein adjusting the brightness of the display panel comprises: determining the target brightness to be lower than a current brightness when the at least one comparison indicates that the temperature is greater than the first threshold temperature and when the current brightness is greater than a minimum acceptable brightness of said at least one acceptable range of brightness; and determining the target brightness to be higher than the current brightness when the at least one comparison indicates that the temperature is less than the second threshold temperature, and when the current brightness is less than a maximum acceptable brightness of said at least one acceptable range of brightness. 8 . The method of claim 4 , wherein the at least one physical property comprises a rate of temperature change and a temperature and the at least one threshold comprises a threshold rate of temperature change a threshold temperature, wherein adjusting the brightness of the display panel comprises: determining the target brightness to be lower than a current brightness when the at least one comparison indicates that the rate of temperature change is greater than the threshold rate of temperature change and the temperature is greater than the threshold temperature and when the current brightness is greater than a minimum acceptable brightness of said at least one acceptable range of brightness; and determining the target brightness to be higher than the current brightness when the at least one comparison indicates that at least one of the rate of temperature change is not greater than the threshold rate of temperature change and the temperature is not greater than the threshold temperature, and when the current brightness is less than a maximum acceptable brightness of said at least one acceptable range of brightness. 9 . The method of claim 5 , wherein the at least one physical property comprises a rate of temperature change and a temperature, the at least one predicted physical property value comprises a predicted temperature value, and the at least one threshold comprises a first threshold temperature and a second threshold temperature, wherein adjusting the brightness of the display panel comprises: determining the target brightness to be lower than a current brightness when the at least one comparison indicates that the predicted temperature value is greater than the first threshold temperature and when the current brightness is greater than a minimum acceptable brightness of said at least one acceptable range of brightness; and determining the target brightness to be higher than the current brightness when the at least one comparison indicates that the predicted temperature value is less than the second threshold temperature, and when the current brightness is less than a maximum acceptable brightness of said at least one acceptable range of brightness. 10 . The method of claim 4 , wherein the at least one physical property comprises a rate of aging and the at least one threshold comprises a first threshold rate of aging and a second threshold rate of aging, wherein adjusting the brightness of the display panel comprises: determining the target brightness to be lower than a current brightness when the at least one comparison indicates that the rate of aging is greater than the first threshold rate of aging and when the current brightness is greater than a minimum acceptable brightness of said at least one acceptable range of brightness; and determining the target brightness to be higher than the current brightness when the at least one comparison indicates that the rate of aging is less than the second threshold rate of aging, and when the current brightness is less than a maximum acceptable brightness of said at least one acceptable range of brightness. 11 . The method of claim 4 , wherein the at least one physical property comprises aging and the at least one threshold comprises a first threshold aging and a second threshold aging, wherein adjusting the brightness of the display panel comprises: determining the target brightness to be lower than a current brightness when the at least one comparison indicates that the aging is greater than the first threshold aging and when the current brightness is greater than a minimum acceptable brightness of said at least one acceptable range of brightness; and determining the target brightness to be higher than the current brightness when the at least one comparison indicates that the aging is greater than the second threshold aging, and when the current brightness is less than a maximum acceptable brightness of said at least one acceptable range of brightness. 12 . The method of claim 4 , wherein the at least one physical property comprises aging and a rate of aging th
