    Abstract: Provided is a display system with which visibility can be improved.
    The display system includes an imaging device, a control device, and a display device. The imaging device includes first pixels arranged in a matrix, and the display device includes second pixels arranged in a matrix. The imaging device has a function of generating first image data on the basis of the illuminance of light emitted to the first pixels. The control device has a function of forming a histogram on the basis of the first image data and dividing the histogram into two or more illuminance ranges. The control device has a function of converting the gray levels which are included in the first image data as information and correspond to the illuminance of the light emitted to the first pixels, thereby generating second image data obtained by performing dynamic range compression on the first image data. The compressibility for the dynamic range compression is calculated for each illuminance range by the control device on the basis of the value of integral in each illuminance range of the histogram.

    Abstract: A semiconductor device is provided; the semiconductor device includes unipolar transistors. A steady-state current does not flow in the semiconductor device. The semiconductor device uses a high-level potential and a low-level potential to express a high level and a low level, respectively. The semiconductor device includes unipolar transistors, a capacitor, first and second input terminals, and an output terminal. To the second input terminal, a signal is input whose logic is inverted from the logic of a signal input to the first input terminal. The semiconductor device has a circuit structure called bootstrap in which two unipolar transistors are connected in series between the high-level potential and the low-level potential and a capacitor is provided between an output terminal and a gate of one of the two transistors. A delay is caused between the gate of the transistor and the signal output from the output terminal, whereby the bootstrap can be certainly performed.

    Abstract: To provide a display device with high display quality, an eye-friendly display device, a display device with low power consumption, a display device with a reduced change in voltage written to a pixel, or a novel display device. In the display device, a first image signal in which one of grayscale levels of a first pixel and an adjacent second pixel is near white and the other is near black is written. The first image signal is compared with a second image signal. When the grayscale levels of the second image signal written to the first pixel and the second pixel are halftone, the second image signal is written an odd number of times greater than or equal to three times. When the grayscale levels of the second image signal written to the first pixel and the second pixel are near white or near black, the second image signal is written once. The interval between the writing of the first image signal and the writing of the second image signal is longer than or equal to 1 second and shorter than or equal to 10,000 hours.

    Abstract: To provide an information processing system allowing eye-friendly display. The information processing system includes a liquid crystal display device (LCD) as a display unit. An image can be displayed in the LCD by at least two driving methods: a first driving method in which data is sequentially rewritten every frame; and a second driving method in which rewriting of data is stopped after data is rewritten once or more times at the same refresh rate as the first driving method. After the display by the second driving method, each pixel is inversely driven plural times by a signal with an amplitude greater than or equal to 80% and less than or equal to 100% of the maximum amplitude of the data signal, whereby degradation of a liquid crystal material is repaired.
