摘要： An OLED display substrate, a method for manufacturing the same, and a display device are provided. The OLED display substrate includes multiple sub-pixels, and at least one sub-pixel includes: an anode, a cathode, and a light-emitting layer between the anode and the cathode. The anode includes: a light-reflective layer and a first transparent conductive layer covering the light-reflective layer, and the first transparent conductive layer is located between the light-reflective layer and the light-emitting layer. First vertical distances between first surfaces of the first transparent conductive layers of the subpixels of different colors facing the respective cathodes and the respective cathodes are the same, and second vertical distances between the first surfaces of the first transparent conductive layers of the subpixels of different colors and second surfaces of the respective light-reflective layers facing the respective cathodes are different.

摘要： The present disclosure provides a light source, a backlight module and a display apparatus. The light source includes: a light emitting diode chip; and a fluorescent powder layer arranged to face towards the light emitting diode chip and configured to receive a first light emitted from the light emitting diode chip and to emit a second light with a wavelength different from that of the first light, wherein the light emitting diode chip and the fluorescent powder layer are moveable with respect to each other such that quantity of fluorescent powder in the fluorescent powder layer excited by the light emitted from the light emitting diode chip increases or decreases. In the above solution, the light emitting diode chip and the fluorescent powder layer are movable with respect to each other, so as to adjust color temperature of backlight conveniently.
