    Abstract: The present invention discloses a display device and a display method. A voltage adjustment circuit is configured to compare whether a difference between absolute values of a first data voltage signal and a second data voltage signal at a preset moment exceeds a set threshold range and output a control signal to a voltage adjustment circuit when the difference exceeds the set threshold range. Thus, a first data latch and update signal of a first source driver chip is adjusted by the voltage adjustment circuit, or a second data latch and update signal of a second source driver chip is adjusted, so that the first data voltage signal and the second data voltage signal are respectively output to a first data line and a second data line at a same time.
