  • Publication number: 20180366073
    Abstract: It is provided a grayscale voltage debugging method for debugging a display device including a white subpixel, including a first step of, in a state where the white subpixel is disenabled and subpixels in other colors are enabled, adjusting a respective to-be-adjusted grayscale voltage applied to each of the subpixels in other colors, so that a first actually-measured Gamma curve corresponding to the respective adjusted grayscale voltage is located within an acceptable range of a standard Gamma curve, and a second step of, in a state where the white subpixel and the subpixels in other colors are all enabled, acquiring a second actually-measured Gamma curve and in the case that the second actually-measured Gamma curve is not located within the acceptable range, changing the respective adjusted grayscale voltage to obtain a new respective to-be-adjusted grayscale voltage, and returning to the first step.

    Abstract: A thin film transistor comprises a gate, a gate insulating layer, an active layer, a source electrode and a drain electrode. The drain electrode comprises a first sub-drain electrode and at least one second sub-drain electrode. A first portion of the active layer between the first sub-drain electrode and the source electrode and a second portion of the active layer between each of the at least one second sub-drain electrode and the source electrode are used for forming different portions of a primary channel, respectively. The first sub-drain electrode is a signal input electrode, and a third portion of the active layer between the first sub-drain electrode and each of the at least one second sub-drain electrode is used for forming an auxiliary channel. A channel length of the auxiliary channel is less than or equal to a channel length of the primary channel.
