Abstract

The embodiment of the invention provides a test method and a test device of a display panel, and a display device, relates to the technical field of display, and aims to improve the color cast phenomenon of the display device under a side view angle. The test method of the display panel comprises the following steps: outputting a first data signal to the display panel, enabling the display panel to display a first white picture, enabling a color coordinate under a positive view angle to meet a white balance condition, testing a color coordinate of the first white picture under a first side view angle, solving a first color cast value, and when the first color cast value does not meet a color cast condition, executing the following steps: outputting a second data signal to the display panel to enable the display panel to display a second white picture, testing the color coordinate of the second white picture under the first side view angle and the color coordinate of the second white picture under the positive view angle, and solving a second color cast value and a third color cast value, wherein the color coordinate of the second white picture under the second side view angle meets the white balance condition; and taking the corresponding second side view angle as a target side view angle until the second color cast value and the third color cast value meet a color cast condition.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a test method, a test device and a display device of a display panel. Background technique [0002] Display devices, such as organic light-emitting diode (Organic Light-Emitting Diode, OLED for short) display devices, are used in more and more diverse scenarios. For example, an OLED display device can be used as a vehicle display device (such as a central control display screen, an instrument display screen, etc.). [0003] see figure 1 , in the use of the vehicle, the user (such as the driver) usually watches the vehicle display device from a certain side viewing angle. For example, if figure 1 As shown in (a), the central control display screen is usually set in the center of the vehicle dashboard, and the driving seat of the vehicle is usually located on one side of the vehicle, that is, the central control display screen is usually located on the side of the driving seat....
