Abstract
Liquid crystal display device ( ) (particularly having a low threshold voltage) provided with means ( ) for compensating the temperature dependence of characteristic voltages of the display device by adapting the frequency at which the pixels are driven. The voltages to be used then do not need to be adapted, notably if they are determined once for the highest occurring drive frequency (which generally occurs at the highest operating temperature).
