Embodiment 1

[0063] An embodiment of the present invention provides a display panel, including: a display unit and a sensing unit for detecting the brightness of the display unit. The sensing unit and the display unit are synchronously formed on different regions of the same substrate.

[0064] The display panel provided by the embodiment of the present invention includes a plurality of display units, and also includes sensing units synchronously formed on different regions of the same substrate, and the sensing units are used to detect the brightness of some display units, so as to realize brightness detection and compensation function. Generally speaking, a display unit mainly includes a display device, a thin film transistor and a signal line for controlling the operation of the display device, while the main component of a sensing unit is a photosensitive device, and the electrodes of the photosensitive device and the signal lines connected to the electrodes can be connected The metal ...

Embodiment 2

[0086] This embodiment provides a method for manufacturing a display panel, including: providing a base substrate; forming a display unit in the display area of ​​the base substrate; Simultaneously form the sensing unit.

[0087] Therefore, in the display panel provided by this embodiment, the sensing unit used to detect the brightness of the display unit is formed synchronously with the display unit, without additional manufacturing process due to the introduction of the sensing unit, and the sensing unit is bent ( Or cut and install) attached to the top cover of the display area, after closing the top cover, the sensing unit covers the display area, then play the test picture to obtain the brightness data, and then play the test picture to obtain the brightness data, obtained by calculation The compensation value is stored and compensated according to the set compensation value after the top cover is opened, so as to solve the problem of uneven brightness.

[0088] Specific...

Embodiment 3

[0093] The embodiment of the present invention also provides a control method of a display device, the display device includes any one of the display panels in the embodiments, that is, the display panel is also provided with a sensing unit synchronously formed with the display unit, and the sensing unit is It is attached to the top cover of the display area by bending (or installing after cutting). The display device control method provided in this embodiment specifically includes:

[0094] Step 1: Trigger the brightness compensation switch to enable the brightness detection and compensation function; optionally, in this step, the brightness compensation switch can be triggered by closing the top cover.

[0095] Step 2: The display panel displays a test picture; optionally, the test picture includes: all white and all black pictures of each primary color, but is not limited thereto, and may also be other test pictures for testing brightness.

[0096] Step 3, collecting and o...

Abstract

The embodiment of the invention discloses a display panel and a manufacturing method thereof and a flexible display device and a control method thereof. The mask film process can be reduced so that production efficiency can be enhanced and cost can be reduced. The display panel comprises display units, and sensing units which are used for detecting brightness of the display units. The sensing units and the display units are synchronously formed in different areas of the same underlying substrate.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a manufacturing method thereof, a display device and a control method thereof. Background technique [0002] Organic Light Emitting Diode (OLED) display is considered to be Emerging technologies for the next generation of flat panel displays. However, as the usage time of the OLED display increases, the luminous brightness of the OLED material decays and the process is unstable, etc., the problem of uneven brightness will gradually appear on the OLED display. [0003] At present, the traditional OLED display with brightness compensation function such as figure 1 As shown, the sensor device 2 is arranged under the light emitting device 1; wherein, the lower electrode 4 of the light emitting device 1 has a hole or is made of a completely transparent material, so that the light emitted by the light emitting material can be detected by the sensor device 2 on the lowe...
