Aspects of the present disclosure directs to inspection of pixels of a display device using photon collection. In certain embodiments, the display device includes a display panel defining multiple pixels in a pixel matrix. A controller divides the pixel matrix into multiple areas, with each area including at least one pixel, and assigns a threshold value for each area. The controller then controls the pixels in one area to emit light displaying a color. A transparent photon collection panel attached to the display panel receives the light displayed by the area, and generates an analog signal in response to the light. An analog to digital (A/D) converter converts the analog signal to a photon current value. The controller receives the photon current values corresponding to each area, and compares the photon current value with the threshold value for each area to determine a flag value for the area. |

1. A display device, comprising:
a display panel, defining a plurality of pixels in a pixel matrix; a controller configured to control the pixels of the display panel, the controller comprising a processor and a non-volatile memory storing computer executable codes, wherein the codes, when executed at the processor, is configured to
divide the pixel matrix into a plurality of areas, wherein each area comprises at least one pixel,assign a threshold value for each of the areas,control the pixels in one area to emit light displaying a color, and in response, receive a photon current value corresponding to the area, andcompare, for each of the areas, the photon current value with the threshold value to determine a flag value for the area; a transparent photon collection panel attached to the display panel, wherein the transparent photon collection panel is configured to receive the light displayed by the area and to generate an analog signal in response to the light; and an analog to digital (A/D) converter electrically connected to the transparent photon collection panel and the controller, wherein the A/D converter is configured to receive the analog signal from the transparent photon collection panel, to convert the analog signal to the photon current value, and to send the photon current value to the controller. |
