Abstract

The present application provides a display panel and a display device. The display panel includes a plurality of pixel units, wherein each of the pixel units includes a sub-pixel, the sub-pixel includes a first micro-LED chip, and in a top view, a gap is provided between adjacent ones of the first micro-LED chips; and a functional element disposed at the gap, wherein a function of the functional element is different from a display function of the sub-pixel, in order to improve integration of the display panel, increase an added value of the display panel, and save a space of the whole machine.

Claims (12)

1. A display panel, comprising:

a plurality of pixel units, wherein each of the pixel units comprises a sub-pixel, the sub-pixel comprises a first micro-LED chip, and in a top view, a gap is provided between adjacent ones of the first micro-LED chips; and

a functional element disposed at the gap,

wherein a function of the functional element is different from a display function of the sub-pixel,

wherein the functional element comprises a biometric unit, an antenna unit, an energy storage unit, a storage unit, a logic unit, a pressure detection unit, or a combination thereof,

wherein the biometric unit comprises a fingerprint identification unit, the fingerprint identification unit comprises a fingerprint identification sensor, the display panel further comprises an optical path element, the fingerprint identification sensor is disposed at the gap, and the optical path element is correspondingly disposed above the fingerprint identification sensor.

2. The display panel according to claim 1 , wherein lengths and widths of the first micro-LED chips range from 1 micrometer to 100 micrometers, and heights of the first micro-LED chips range from 1 micrometer to 20 micrometers.

3. The display panel according to claim 1 , wherein an area of the fingerprint identification sensor ranges from 10 square microns to 800 square microns.

4. The display panel according to claim 1 , wherein a distance between the fingerprint identification sensor and each of the first micro-LED chips ranges from 1 micrometer to 10 micrometers.

5. The display panel according to claim 1 , wherein the biometric unit comprises a near-infrared light sensor and a second micro-LED chip, wherein the second micro-LED chip is configured to emit near-infrared light to provide the near-infrared light sensor with a light source, and the near-infrared light sensor and the second micro-LED chip are disposed together at the gap.

6. The display panel according to claim 5 , wherein a size of the second micro-LED chip is smaller than a size of each of the first micro-LED chips.

7. The display panel according to claim 6 , wherein the size of the second micro-LED chip is one half or one third of the size of each of the first micro-LED chips.
