A display control method for a display panel implemented in a display control device, comprising: detecting (S1) whether the display panel is in a low brightness mode if a first brightness of the display panel is less than a first preset brightness threshold and whether the display panel is in a low ambient mode if a second brightness of an ambient light in an environment where the display panel is located is less than a second preset brightness threshold; and enabling (S2) an eye protection mode when the first brightness of the display panel is less than the first preset brightness threshold and the brightness of the ambient light in the environment where the display panel is located is less than the second preset brightness threshold; wherein enabling (S2) the eye protection mode comprises: reducing (S21) brightness of a blue sub-pixel in a pixel unit of the display panel, and adjusting brightness of one or more other sub-pixels in the pixel unit, according to a blackbody trajectory and reduced brightness of the blue sub-pixel to reduce brightness of the pixel unit by 10% to 20% and to enable a chromaticity of light emitted by the adjusted pixel unit to be similar to a chromaticity of light emitted by the pixel unit before adjustment; wherein the blackbody trajectory represents a chromaticity curve of a blackbody at different temperatures in a CIE chromaticity diagram. detecting (S1) whether the display panel is in a low brightness mode if a first brightness of the display panel is less than a first preset brightness threshold and whether the display panel is in a low ambient mode if a second brightness of an ambient light in an environment where the display panel is located is less than a second preset brightness threshold; and enabling (S2) an eye protection mode when the first brightness of the display panel is less than the first preset brightness threshold and the brightness of the ambient light in the environment where the display panel is located is less than the second preset brightness threshold; wherein enabling (S2) the eye protection mode comprises: reducing (S21) brightness of a blue sub-pixel in a pixel unit of the display panel, and adjusting brightness of one or more other sub-pixels in the pixel unit, according to a blackbody trajectory and reduced brightness of the blue sub-pixel to reduce brightness of the pixel unit by 10% to 20% and to enable a chromaticity of light emitted by the adjusted pixel unit to be similar to a chromaticity of light emitted by the pixel unit before adjustment; wherein the blackbody trajectory represents a chromaticity curve of a blackbody at different temperatures in a CIE chromaticity diagram. reducing (S21) brightness of a blue sub-pixel in a pixel unit of the display panel, and adjusting brightness of one or more other sub-pixels in the pixel unit, according to a blackbody trajectory and reduced brightness of the blue sub-pixel to reduce brightness of the pixel unit by 10% to 20% and to enable a chromaticity of light emitted by the adjusted pixel unit to be similar to a chromaticity of light emitted by the pixel unit before adjustment; wherein the blackbody trajectory represents a chromaticity curve of a blackbody at different temperatures in a CIE chromaticity diagram. <EOS>
