Abstract: Provided are a display module and a display device. The display module includes a photosensitive element, a backlight unit, and a backlight. The backlight unit includes a first reflective sheet provided with a first opening corresponding to the photosensitive element, a light guide plate including a first region corresponding to the photosensitive element and a second region adjacent thereto, and an optical film provided with a second opening corresponding to the photosensitive element. A plurality of the microstructures are provided on a side of the light guide plate facing the photosensitive element. A distance between two adjacent columns of the microstructures in the first region is less than a distance between the two adjacent columns of the microstructures in the second region, or in a column of the microstructures, sizes of the microstructures in the first region are greater than sizes of the microstructures in the second region.

Abstract: An embodiment of the present application discloses a display panel manufacturing method and a display panel including a driver transistor, a storage capacitor, a switch transistor, and a sensing transistor vertically stacked. At leas two transistors are vertically stacked to solve a technical issue that a pixel in a conventional display panel employs a pixel circuit design of transistors and capacitors arranged along a direction parallel to the display panel to cause a lowered pixel density of the display panel to result in a lowered resolution of a display panel product.
