A liquid crystal display panel includes a first transparent glass layer; a second transparent glass layer overlapping the first transparent glass layer; two or more pixel units disposed on a side of the first transparent glass layer opposite to the second transparent glass layer, each of the pixel units including a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel arranged in accordance with a predetermined rule; a black matrix disposed between the pixel units to isolate two pixel units adjacent to each other; and a fingerprint sensor disposed on the second transparent glass layer, and covered by the black matrix; when the fingerprint sensor is viewed from the top, an area of the fingerprint sensor corresponding to a region of the red sub-pixels is larger than any one of areas of the fingerprint sensors corresponding to respective regions of the green, blue, and white sub-pixels.

Liquid crystal display panel and smart terminal provided with the same

An in-screen fingerprint identification apparatus includes a display panel and a fingerprint identification module. The display panel includes a backlight module, a liquid crystal layer, and a cover glass, which are sequentially stacked. The cover glass includes a fingerprint identification area. The fingerprint identification module includes a light source, a photosensor, and light guiding layers disposed on the cover glass. The light guiding layers at least cover portions of opposite sides of the cover glass, respectively, such that light emitted by the light source after being reflected in the cover glass is guided to the fingerprint identification area. The photosensor is disposed in the display panel and corresponds to the fingerprint identification area to receive an optical signal of the light source emitted by the light source after being reflected by a finger in the fingerprint identification area.

In-screen fingerprint identification apparatus and electronic device

Aspects of the disclosure provide a display panel that can include a display region, a blind hole arranged in the display region for light passage, and a light-shielding region arranged between the display region and a hole region. The display panel can also include a Photo Spacer (PS) structure that is arranged in a liquid crystal layer in the display region and the light-shielding region for supporting the cell thickness of the liquid crystal layer. The density of the PS structure in the liquid crystal layer increases and then decreases from the display region to the light-shielding region, with the density of the PS structure in the light-shielding region is highest.

Display panel, manufacturing method, and electronic device

A display panel includes a first substrate, a second substrate disposed opposing the first substrate, a first transparent layer, a first light shield layer, and a photosensitive element layer located between the first substrate and the second substrate. The first transparent layer, the first light shield layer, and the photosensitive element layer are sequentially disposed along a direction from the first substrate to the second substrate. The first transparent layer includes a plurality of protrusions extending toward the first substrate. The first light shield layer includes a plurality of first openings, and the photosensitive element layer includes a plurality of photosensitive elements for acquiring a fingerprint image. The protrusions, the first openings, and the photosensitive elements have one-to-one correspondence, and have at least partially overlapped orthographic projections on the second substrate.
