Abstract: A display substrate includes a base substrate and a filter conversion layer disposed on the base substrate. The filter conversion layer includes a light conversion material capable of absorbing light with a wavelength less than a preset wavelength range, and converting the absorbed light into light with a wavelength in the preset wavelength range. The filter conversion layer is configured to allow the light with the wavelength in the preset wavelength range to pass through.
