Problems solved by technology
[0004] When making a curved display, it is necessary to bend the display screen and the backlight module to the same curvature and bond them together, but usually, since the materials of the display screen and the backlight module of the curved display are not exactly the same, the display screen and the backlight module It is difficult for the curvature of the group to be completely consistent, and light leakage will occur in areas with inconsistent curvature, which will affect the brightness uniformity of the curved display

The embodiment of the invention provides a brightness compensation method and a curve surface display device. The method is used in the technical field of displaying and can overcome the light leak phenomenon of the curve surface display device and improve the brightness uniformity of the curve surface display device. The brightness compensation method comprises the following steps: obtaining the brightness value of a non light leak region of the curve surface display device as a reference value; adjusting PWM (Pulse Width Modulation) of a reference backlight LED light bar according to the reference value and a reference brightness value. The brightness compensation method provided by the embodiment of the invention is used for solving the light leak problem of the curve surface display device.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a brightness compensation method and a curved display device. Background technique [0002] At present, the commonly used displays are mainly flat-panel displays, and the retina of the human eye is curved. The distance between the edge area of the direction and the human eye is not equal, which will distort the picture seen by the user and affect the viewing experience of the user. [0003] In order to meet the user's viewing needs, a curved display has appeared in the prior art. The curvature of the display screen of the curved display is approximately the same as that of the retina of the human eye. , the distance from the center area of the curved display to the human eye in the horizontal direction is approximately equal to the distance from the edge area of the curved display to the human eye, so that the picture is intuitively mapped to the brain at the same angle, ...
