Background
In order to prolong the lifetime of an Organic Light Emitting Diode (OLED) display panel, an energy saving (ECO) algorithm is used in the prior art, and after the OLED display panel displays a static image for a period of time, an OLED display device enters an ECO Mode to automatically reduce the brightness of a display screen.

Fig. 2 is a graph showing a graph of luminance versus time of a display screen in a conventional energy saving method for a display panel.
The energy-saving method of the existing display panel comprises the following steps: a static picture judging step, namely judging whether a current picture of the display panel is a static picture, if so, acquiring the brightness of each pixel of the current picture as initial brightness (lum1 and lum2) and executing the next step, and if not, repeating the static picture judging step; and an ECO algorithm executing step of executing an ECO algorithm, wherein the ECO algorithm includes an energy-saving algorithm and can generate a brightness adjustment coefficient (ECO _ target), the energy-saving algorithm operates on the brightness adjustment coefficient (ECO _ target) and the initial brightness to finally obtain target brightness (lum _ target1, lum _ target2) (adjusted brightness) of the current picture, the initial brightness performs an ECO algorithm of the ECO algorithm and substitutes the brightness adjustment coefficient into a specific mathematical equation.
However, in the same frame of the current picture, all pixels apply the same brightness adjustment coefficient (eco _ target), which results in the following two undesirable brightness adjustment situations. If the initial brightness (lum1) of the screen is high, the target brightness (lum _ target1) (adjusted brightness) obtained by the ECO algorithm is relatively high, and a good energy-saving effect cannot be achieved. On the contrary, if the initial brightness (lum2) of the screen is very low, the target brightness (lum _ target2) obtained by the ECO algorithm is very low, which affects the overall display quality of the screen.
