Abstract

The invention discloses a display device. The display device comprises a time sequence controller, a data buffer, a source driver and a display panel, part of vertical effective display line number data is output in a vertical idle period through the data buffer, the total pixel line charging time of the whole frame of image can be prolonged, and meanwhile the uniformity of upper and lower half screen image display is improved by adjusting the N / 2 horizontal idle period to the Nth horizontal idle period.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of display device charging technology, and in particular to a display device and a charging control method applied to the display device. Background technique [0002] With the increasing size of display devices, the resolution is also getting higher and higher. For example, the charging problem of large-sized UD (Ultra High Definition, ultra-high definition) and 8k (referring to resolution) operating at a frequency of 120Hz It is becoming more and more serious. Due to the resistance and capacitance consumption and delay of the metal wiring that transmits data signals inside the panel, the charging rate of the pixel row from near to far from the source driver gradually deteriorates, causing the display device to display images. The difference in the lower half of the screen is obvious. Contents of the invention [0003] The present application provides a d...
