The application provides an LED straight tube lamp, comprising: a lamp tube, the lamp tube comprising a diffusion coating covering the inner circumferential surface of the lamp tube; a lamp cap arranged at one end of the lamp tube; a lamp plate arranged in the lamp tube, the lamp plate being provided with a light source; a power supply, the power supply being in electrical communication with the light source through the lamp plate, the power supply comprising a circuit board and a power supply module arranged on the circuit board; the lamp plate is a flexible circuit board or a flexible substrate, the lamp plate having a part fixed on the inner circumferential surface of the lamp tube and a part located at both ends of the lamp plate and not fixed on the inner circumferential surface of the lamp tube, wherein the part not fixed on the inner circumferential surface of the lamp tube forms a free part, one end of the free part is deformed by being contracted towards the inside of the lamp tube, and the free part is directly welded to the circuit board of the power supply, the free part being an integral part of the flexible circuit board or the flexible substrate.

This application discloses a driving method and driving system for a display panel, as well as a display device. The display panel includes multiple pixels, each pixel including a red sub-pixel, a green sub-pixel, and a blue sub-pixel. The driving method includes: acquiring image information of an initial image, the image information including initial grayscale values ​​corresponding to three sub-pixels of at least one pixel, each initial grayscale value corresponding to a target grayscale value, the target grayscale value including a first target grayscale value and a second target grayscale value, the magnitude of the initial grayscale value being between the first target grayscale value and the second target grayscale value; determining whether at least three initial grayscale values ​​are all equal; if not, calculating the grayscale difference between the maximum value among the at least three initial grayscale values ​​and the initial grayscale value corresponding to a sub-pixel of at least one other color under preset conditions; acquiring the number of sub-pixels displayed with the initial grayscale value and the number of sub-pixels displayed with the target grayscale value based on the grayscale difference, so as to display a target image.

The application provides a pixel arrangement structure and a display panel. The pixel arrangement structure comprises at least one pixel group, the pixel group comprises a plurality of sub-pixels arranged in an array; in the pixel group, the number ratio of high gray scale sub-pixels to low gray scale sub-pixels is 1:2 or 1:3; the low gray scale sub-pixels comprise first low gray scale sub-pixels, and the number of high gray scale sub-pixels and the number of first low gray scale sub-pixels in every adjacent N rows of the sub-pixels are equal, N is an integer multiple of 2, an integer multiple of 3 or 1. The application can improve the visual effect while improving the view angle compensation effect and weakening the picture grain feeling.

The application discloses a display compensation method and system, a display device and a storage medium. The compensation method is applied to a display panel, the display panel is divided into N display partitions which are the same in size and do not overlap with each other, wherein N is a positive integer greater than 1, and the compensation method comprises the following steps: obtaining charging rates of the N display partitions; obtaining N target gray scale compensation tables according to the charging rates of the display partitions and a preset gray scale compensation table; and performing brightness compensation on the display partitions according to the target gray scale compensation tables. The application performs high-low gray scale compensation processing on different regions to different degrees, reduces the particle feeling, improves the display quality, reduces the consumption of storage resources and the manufacturing cost.
