    • An image display with high brightness where a long time can be secured for light emission of self-luminous elements can be implemented using only line memories.The period for the writing in of a display voltage (period for writing in of data) continues for a number of lines (three lines), and the reset pulse becomes of a “high” state. Subsequently, operation for three lines is carried out collectively during a triangular wave period (period for writing in of a triangular wave voltage), and only the light emission controlling pulse becomes of a “high” state. During the period for the writing in of a triangular wave voltage, the writing in of a triangular wave voltage from the second time onward is rewriting of a triangular wave voltage, and thus, the period for rewriting the display voltage (dotted line portion) becomes unnecessary, and a longer period for light emission, where the light emission controlling pulse becomes of a “high” state, can be secured.
    • 可以仅使用行存储器来实现具有高亮度的长时间可以确保自发光元件的发光的图像显示器。 用于写入显示电压的周期(数据写入周期)持续多行(三行),并且复位脉冲变为高状态。 随后,在三角波周期(写入三角波电压的周期)中集中进行三线的操作,并且只有发光控制脉冲变为高状态。 在写入三角波电压的期间中,从第二次开始写入三角波电压是三角波电压的重写,因此,重写显示电压(虚线部分)的周期成为 可以确保发光控制脉冲变为高状态的发光的不必要的和更长的周期。

    • With the use of pixel control parts for controlling display elements in response to display data using a display-use voltage source and display control parts for supplying the display data to the pixel control parts, the display data is displayed on a display part. Further, the display data is corrected by detecting states of the display elements. A voltage of the display-use voltage source is preliminarily set to a fixed higher voltage, and a gray scale of the display data is elevated in response to a degradation state of the display element. Accordingly, it is possible to perform a display while maintaining the maximum brightness even when the display element is degraded. Further, the contrast can be maintained by correcting the gray scales of the display data by performing only the digital calculation.
    • 通过使用用于使用显示用电压源和显示控制部件响应于显示数据来控制显示元件的像素控制部件,用于将显示数据提供给像素控制部件,显示数据被显示在显示部分上。 此外,通过检测显示元件的状态来校正显示数据。 显示用电压源的电压被预先设定为固定的较高电压,并且响应于显示元件的劣化状态而升高显示数据的灰度。 因此,即使显示元件劣化,也可以在保持最大亮度的同时进行显示。 此外,可以通过仅执行数字计算来校正显示数据的灰度级来维持对比度。
