Problems solved by technology

For example: the flexible display screen will inevitably have the junction and transition between the planar area and the bending area, and the current flexible display screen generally uses a single-sized pixel, so that the bending area has a relatively curved surface due to its flexible carrier (in the present invention, the bending area The bending area can be understood as a curved surface with a certain bending angle), which is prone to image distortion and deformation distortion, resulting in the resolution and definition of the bending area being far inferior to that of the flat area, resulting in visual errors

Embodiment 1

[0029] This embodiment provides a flexible substrate, such as figure 1 As shown, the flexible substrate includes a planar area 10 and a bending area 20, and pixels 1 are arranged in both the planar area 10 and the bending area 10, wherein the arrangement density of the pixels 1 in the bending area 20 is greater than that of the pixels in the planar area 10 The permutation density of 1.

[0030] That is, the technical idea of ​​the present invention is that in order to achieve higher resolution and clarity of the displayed image in the bending area 20, different pixel matrices can be used in the plane area 10 and the bending area 20, for example: in the bending area 20. There is a relatively high requirement for picture clarity, and a small-size, high-density pixel matrix is ​​used; in the flat area 10 (or non-bending area), the requirements for picture clarity are relatively low, and large-size, low-density pixels are used matrix.

[0031] A preferred solution is to make the...

Embodiment 2

[0048] This embodiment provides a flexible substrate, which differs from the flexible substrate in Embodiment 1 in that the arrangement density of the pixels 1 in the bending region 20 in this embodiment is from the central part far away from the planar region 10 to near the planar region 10 The peripheral part gradually becomes smaller. That is to say, the arrangement density of the pixels 1 in the bending region 20 in this embodiment is not constant.

[0049] Compared with Embodiment 1, the flexible substrate of this embodiment provides a more flexible arrangement of pixels. According to the curvature of the curved surface of the bending region, the part with the largest curvature in the central part of the bending region can be set to have the largest The pixel density is lower, and the portion with smaller curvature near the plane area is set to have a smaller pixel density, so that the displayed image can be displayed in a progressive manner, so that people can obtain bet...

Embodiment 3

[0051] This embodiment provides a display device, which is the flexible substrate exemplified in Embodiment 1 or Embodiment 2.

[0052] Wherein, the pixels in the flexible substrate may include self-luminous OLED devices, and may also include liquid crystals that cooperate with a backlight source to realize image display.

[0053] The display device includes liquid crystal panels, electronic paper, OLED panels, mobile phones, tablet computers, televisions, monitors, notebook computers, digital photo frames, navigators, smart cards, smart labels and any other products or components with display functions.

[0054] The invention provides a technical scheme of using non-equal-density pixel matrix in the plane area and bending area on the flexible substrate. By using pixels of different types or sizes, image distortion and distortion are reduced, and solid-state flexibility is improved. The resolution and definition of the display picture in the bending area of ​​the display scree...

Abstract

The invention belongs to the field of display technologies and particularly relates to a flexible substrate and a display device. The flexible substrate comprises a plane are and a bent area. Each of the plane area and the bent area is provided with pixels. Arrangement density of the pixels in the bent area is larger than that of the pixels in the plane area. The flexible substrate has higher resolution and definition of displayed pictures; meanwhile, the resolution and definition of the display device is increased; better visual experience is brought to people.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a flexible substrate and a display device. Background technique [0002] Flat panel display technology has developed rapidly in the past ten years, and liquid crystal display devices (Liquid Crystal Display: LCD) and organic electroluminescent display devices (Organic Light-Emitting Diode, OLED) have become mainstream flat panel display devices. [0003] With the further development of science and technology, flexible devices have been widely used in people's daily life. Flexible electronic devices, especially flexible display devices (also known as flexible display devices), are widely used in fields that require curved displays, such as smart cards, electronic paper, smart Label applications, etc., cover almost all applications that traditional display devices can apply, and have gradually become the new favorite in the field of display technology. [0004] In a ...
