Abstract: A display device includes a display, a driver, a memory, and a controller. The display includes a display panel and a backlight unit with a plurality of light-emitting elements to display an image. The driver is electrically connected to the display to transmit a backlight control signal to the backlight unit. The memory stores a plurality of adjustment instructions, and each adjustment instruction includes a drive frequency and a control parameter. The controller is electrically connected to the display, the driver, and the memory. The controller is configured to determine a drive frequency and a control parameter corresponding to the drive frequency in the memory according to a frequency adjustment signal, and then adjust the backlight control signal according to the control parameter, to change a duty cycle of the backlight control signal, so that a refresh rate of the backlight unit meets a requirement of a user.

Abstract: A monitor with reminder sounds is disclosed. The device includes at least a monitor, at least a touch button and an audio player. The touch button is disposed on the monitor for adjusting status of the monitor. The audio player is also arranged on the monitor and is connected with the touch button. When pressing the touch button, the audio player receives a signal and makes a sound. The monitor further includes a detection module that is used to check output image signals of the monitor. When detecting errors of output image signals of the monitor, the detection module sends a detection signal to the audio player so as to make the audio player generate a sound. Thus the user is reminded that whether the touch button is pressed precisely. Furthermore, the device also informs the user that the monitor is in abnormal status. Therefore, the present invention provides users more convenience of use.
