Optical compensation strip, display panel, display device and driving method

A spliced display device, comprising:

• at least two sub-display panels, and at least one optical compensation strip;
• wherein
• each of the at least one optical compensation strip is located on a light emitting surface of two adjacent sub-display panels and covers a seam between the two adjacent sub-display panels;
• and
• each of the at least one optical compensation strip comprises:
• a display cover plate, and at least two prisms disposed opposite to the display cover plate, the display cover plate being fixed on a light emitting surface of the adjacent two sub-display panels, and the at least two prisms being located between the display cover plate and the light emitting surface;
• wherein
• a gap is present between each of the prisms and the display cover plate, and each of the prisms, the display cover plate, and the seam all extend along a first direction;
• and
• the at least two prisms are configured to refract light emitted from the two adjacent sub-display panels to an area of the display cover plate corresponding to the seam.

A display device, comprising:

• at least two sub-display panels, at least one optical compensation strip, and at least two backlight modules in a one-to-one correspondence with the at least two sub-display panels;
• wherein
• each of the at least one optical compensation strip is located on a light emitting surface of two adjacent sub-display panels and covers a seam between the two adjacent sub-display panels;
• and each of the at least two backlight modules is located at a light incident surface of the sub-display panel corresponding thereto;
• and
• each of the at least one optical compensation strip includes:
• a display cover plate, and at least two prisms disposed opposite to the display cover plate, the display cover plate being fixed on a light emitting surface of the adjacent two sub-display panels, and the at least two prisms being located between the display cover plate and the light emitting surface;
• wherein
• a gap is present between each of the prisms and the display cover plate, and each of the prisms, the display cover plate, and the seam all extend along a first direction;
• and
• the at least two prisms are configured to refract light emitted from the two adjacent sub-display panels to an area of the display cover plate corresponding to the seam.
