Problems solved by technology

[0005] However, at the moment of switching between the normal brightness display mode and the high brightness display mode, changing different gamma curves will cause the brightness of the picture displayed on the display device to suddenly change, and cannot present a gradual change, seriously affecting The user's visual experience when watching

Embodiment Construction

[0031] A specific embodiment according to the present invention is a display mode conversion method. In this embodiment, the display mode conversion method is applied to the display driving circuit in the display device. The display driving circuit can switch between the first display mode and the second display mode, so that the display device can display images in the first display mode and the second display mode respectively.

[0032] In fact, the first display mode and the second display mode can be display modes that provide different brightness. For example, the first display mode is a normal brightness display mode and the second display mode is a high brightness display mode, or the first display mode is a high brightness display mode. The brightness display mode and the second display mode is the normal brightness display mode, but not limited to this.

[0033] It should be noted that although this embodiment takes the first display mode and the second display mode as ex...

Abstract

A display mode conversion method applied to a display driving circuit is disclosed. The display driving circuit is switched between a first display mode and a second display mode. The display mode conversion method includes steps of: (a) finding a ratio setting when the second display mode displays a default brightness according to the default brightness under the first display mode; (b) when receiving a first mode switching command under the first display mode, gradually adjusting to the default brightness; (c) switching to the second display mode and maintaining displaying the default brightness according to the ratio setting; and (d) under the second display mode, gradually adjusting from the default brightness to a target brightness.

Description

Technical field [0001] The present invention relates to a display driving circuit, and in particular to a display mode conversion method applied to the display driving circuit. Background technique [0002] Generally speaking, when the display driving circuit in the conventional display device switches between different display modes, the display driving circuit will use different gamma curves to achieve different levels of display brightness. [0003] For example, assuming that the display driving circuit is originally in the normal mode (Normal mode), when the display driving circuit receives the display mode switching command, the display driving circuit will switch from the normal brightness display mode to the high brightness display mode (High brightness mode). ,HBM) and load the gamma curve corresponding to the high-brightness display mode. [0004] Similarly, assuming that the display drive circuit is originally in high-brightness display mode, when the display drive circuit...
