Problems solved by technology

[0004] However, since the minimum step (span) of the Power IC's output is limited to 0.1V, that is, the minimum voltage range of ELVSS is 0.1V, and the corresponding brightness span is large, which makes the brightness change suddenly when customers switch DBV, resulting in poor experience. good

Abstract

The invention discloses an OLED display device and a brightness driving method thereof. The OLED display device comprises a display panel, a display brightness value adjusting unit and a data driving unit. The display brightness value adjusting unit is electrically connected with the display panel and is configured to adjust a display brightness value in a preset display brightness value interval; wherein the preset cathode voltage interval of the display panel is correspondingly configured with the preset display brightness value interval and comprises at least one voltage switching point; the data driving unit is electrically connected with the display panel and the display brightness value adjusting unit, and is configured to receive the display brightness value and output different data voltages to the display panel according to whether the display brightness value is equal to the display brightness value configured corresponding to the voltage switching point. The brightness difference between any two adjacent display brightness values is within the preset range. The brightness change corresponding to the preset display brightness value interval can be finer and smoother, the display effect is effectively improved, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display device and a brightness driving method thereof. Background technique [0002] In order to provide users with a good user experience, a display brightness value (displaybrightness value, DBV) for adjusting the brightness of an OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panel may be preset in the electronic device, for example, the display may be preset The value range of the brightness value, the user can adjust the brightness of the display panel by changing the DBV of the OLED display panel. For example, when the light is strong, the user can increase the DBV of the OLED display panel so that the user can clearly see the content displayed on the OLED display panel; when the light is weak, the user can reduce the DBV of the OLED display panel to avoid environmental The brightness difference between the light and the displ...
