However, because the energy consumption of different backlight areas is different, for example, the display position of the "Taiwan logo" will always be in the same state for the backlight, and for the highlighted "Taiwan logo", the LED lights in the backlight area of the logo will always be in the same state. In a continuously bright state, there is irreversible aging loss of the LED lights and even the light board in this area, resulting in uneven brightness display in the backlight area

The invention relates to a backlight compensation method and device of a display screen, display screen equipment and a storage medium. The method comprises the following steps: detecting and identifying a target display page in a display screen, and obtaining display position information of a station caption in the target display page; determining a backlight area of the station logo according to the display position information, wherein the backlight area comprises backlight area information; analyzing the backlight area information, and judging whether the backlight area needs to be compensated or not; if the backlight area needs to be compensated, performing brightness compensation on the backlight area according to a preset strategy; according to the method, the target display page in the display screen is analyzed, the highlight station caption area is identified, and the backlight area of the station caption is compensated, so that the problem that the brightness of the backlight area of the display screen is not uniform due to serious loss and aging of LED lamp beads in the station caption area is solved, and the display quality is improved. And the risk of abnormal display caused by uneven loss of the backlight area of the display screen is reduced.
Description
Technical field [0001] The present application relates to the field of display, and in particular to a backlight compensation method, apparatus, display device, and storage medium of a display screen. Background technique [0002] With the continuous development of mobile communication technology, smart display devices (such as smartphones, tablets, etc.) have become an indispensable product in our lives. Currently, LCD (LCD) is mainstream technology used by the smart display device. MINILED (Mini Light Emitting Diode, Mini Light Emitting Diode) Combined with Local Dimming (local dimming) technology, the regional brightness adjustment can be adjusted, making black clearance, white white, colorful, and brings better visual experience. It is an important trend in the development of LCD products in recent years. However, since the energy consumption of different backlight regions has different differences, such as the "Table" display position is in the same state, and for high-brigh...
