摘要： It is an object to provide a display device in which a problem of light leakage from a liquid crystal element in black display is reduced or overcome and the contrast is improved. It is another object to provide a pixel circuit having a function to control a lighting state of a backlight based on each pixel. These objects are achieved by turning off a light-emitting element in display of a black gray scale, and by providing a light-emitting element in each pixel and providing, in a pixel circuit, a function to individually control lighting and non-lighting of the light-emitting element depending on a gray scale to perform display. When a backlight is provided in each pixel, a light-emitting element that is a backlight is turned off when a black gray scale is displayed, whereby reduction in contrast due to light leakage from a liquid crystal element can be prevented.

摘要： It is an object to provide a display module which can display a correct gray scale by a field sequential driving method and an electronic device including the display module. One frame period is divided into a plurality of lighting periods, and in each of the plurality of lighting periods, signals are supplied to a pixel a plurality of times, whereby the transmissivity of a liquid crystal element is changed over time. Accordingly, even with the use of a liquid crystal element with low response speed as a display element, a correct gray scale can be expressed. In addition, the transmissivity of the liquid crystal element is set at 0% or a backlight is controlled not to emit light in switching of lighting of a backlight or switching of lighting periods, whereby a more correct gray scale can be expressed.

摘要： In a display element such as an organic EL element, deterioration progresses due to light emission, and emission luminance is lowered even if the same voltage is applied to the display element. Therefore, use over time causes variations in luminance of each pixel, thereby a so-called “image burn-in” phenomenon occurs. Given this factor, the invention provides a display device which can reduce the difference in deterioration of a display element in each pixel and suppress variations in light emission of a display element in a pixel. It is prevented that only a specific pixel has a long accumulated lighting time. For that purpose, a gray scale of a display pattern is changed to prevent the difference in deterioration of display element in pixels from increasing. Alternatively, a specific display pattern is prevented from being fixedly displayed in a specific region. Further alternatively, a pixel lagging behind in deterioration is deteriorated so that the accumulated lighting time of pixels is equal to each other.

摘要翻译： 在诸如有机EL元件的显示元件中，由于发光而劣化进行，并且即使对显示元件施加相同的电压，发光亮度也降低。 因此，随着时间的推移导致每个像素的亮度变化，从而发生所谓的“图像老化”现象。 鉴于这个因素，本发明提供一种能够减少每个像素中的显示元件的劣化差异并抑制像素中的显示元件的发光变化的显示装置。 防止只有特定像素具有长的累积点亮时间。 为此，改变显示图案的灰度级以防止显示元件在像素中的劣化的差异增加。 或者，防止特定显示图案被固定地显示在特定区域中。 此外，劣化后退的像素劣化，使得像素的累积点亮时间相等。
