Embodiment 1

[0023] like figure 2 As shown, this embodiment provides a display panel, including: an array substrate 100 , a printed circuit board 300 , and a chip-on-chip film 200 . 400 , the other end is attached to the printed circuit board 300 , and the side of the COF 200 with the chip 201 faces the array substrate 100 , and the connection area 400 is located on the side of the array substrate 100 away from the light-emitting surface.

[0024] One end of the chip-on-film 200 with the chip 201 is attached to the connection area 400 , that is, the way of internal attachment (that is, the chip faces the array substrate), and the other end is attached and connected to the printed circuit board 300 . Compared with the prior art, the method of this embodiment can place the printed circuit board 300 on the back of the array substrate 100 without folding the COF 200 by 180 degrees. Since there is no folding area in this design, the display panel The frame of the display device is narrowed, a...

Embodiment 2

[0032] This embodiment provides a display device, including the above-mentioned display panel. The display device can be any product or component with a display function such as an OLED panel, a mobile phone, a tablet computer, a television set, a monitor, a notebook computer, a digital photo frame, a navigator, etc. .

[0033] The display device in this embodiment has the display panel in Embodiment 1, so the frame of the display device is narrower and the thickness is thinner.

[0034] Of course, the display device of this embodiment may also include other conventional structures, such as a power supply unit.

Abstract

A display panel and a display device having same. The display panel comprises an array substrate (100), a printed circuit board (300) and a chip-on-film (200), wherein one end of the chip on film (200) is attached to a connection region (400) of the array substrate (100), and the other end thereof is attached onto the printed circuit board (300); and the side of the chip-on-film (200) which is provided with a chip (201) faces the array substrate (100). The connection region (400) is located at the side of the array substrate (100) away from an out-light surface.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a display device thereof. Background technique [0002] Flat panel displays are currently the most popular displays, and AMOLED display devices are widely used in electronic products such as computer screens and mobile phones because of their thin and light appearance, power saving and no radiation. [0003] The AMOLED display panel mainly includes an array substrate, a chip-on-film (COF, ChipOn Film) and a printed circuit board (PCB); the array substrate has a display area for display and a connection area (Fan Out) located on the periphery of the display area. The terminal of the middle lead is located in the connection area; the chip on one side is provided with a lead and a chip, which is used to connect the lead in the connection area of ​​the array substrate to the printed circuit board through these leads and the chip. [0004] like figur...
