Description
Technical Field
The invention relates to the technical field of display, in particular to a Mura compensation method of a liquid crystal display device and the liquid crystal display device.
Background
Liquid Crystal Display (LCD) devices have many advantages such as thin body, power saving, and no radiation, and are widely used. Most of the existing liquid crystal display devices in the market are Backlight liquid crystal display devices, which include a liquid crystal display panel (LCD panel) and a Backlight Unit (BLU). Generally, a Liquid Crystal display panel is composed of a Color Filter (CF) substrate, a Thin Film Transistor (TFT) array substrate, Liquid Crystal (LC) sandwiched between the Color Filter substrate and the TFT array substrate, and a Sealant frame (Sealant), and has a working principle that Liquid Crystal molecules are placed between two parallel glass substrates, and the orientation of the Liquid Crystal molecules is controlled by whether the glass substrates are powered on or not, so that light of a backlight module is refracted out to generate a picture.
With the development of LCD towards lighter, thinner and bigger, due to some uncontrollable factors in the actual process, the physical characteristics of the LCD display panel are different, resulting in a non-uniform brightness phenomenon when displaying a pure gray image in a range larger than one pixel point, which is referred to as Mura phenomenon in the industry. The Mura phenomenon has become a bottleneck restricting the development of LCDs. The occurrence probability of the Mura phenomenon can be reduced by methods of improving the process level or improving the purity of raw materials and the like.
For the LCD display Panel (Panel) which is already manufactured, the physical characteristics are already shaped, and in order to compensate for the Mura phenomenon generated by the flaws in the LCD manufacturing process, the brightness of the pixel points can be corrected by a gray compensation mode, so that the Mura phenomenon is improved. Gray compensation is the improvement of brightness uniformity achieved by changing the gray values of the pixels: the Mura condition of a gray level picture is shot by a camera, then a normal area and a Mura area in the gray level picture are determined, finally the gray level of the Mura area is reversely compensated according to the gray level of the normal area, when a pure gray level picture is displayed, as shown in figure 1, a lower gray level is applied to a pixel with higher display brightness, and a higher gray level is applied to a pixel with lower display brightness, so that the brightness of each pixel after gray level compensation is close to be consistent, and the improvement of the Mura phenomenon is realized. Usually, Mura compensation data (reduced or improved gray values) are stored in Flash memories (Flash memories) matched with LCD display panels one by one, and after the Mura compensation data are obtained by a TCON (screen driver board) IC (integrated circuit) chip, the brightness of the LCD is compensated to achieve a normal display effect.
At present, most of LCD panel manufacturers only sell panels, BLUs are manufactured by television manufacturers, and before selling the panels, the LCD panel manufacturers need to match the panels with fixed BLUs with high brightness uniformity to form a temporary liquid crystal display device, and carry out Mura repair on the panels, so that the phenomenon that the actual Mura compensation data of the LCD panels are influenced by the fixed BLUs due to the large brightness and darkness difference is avoided.
However, BLU manufactured by television manufacturers certainly have differences in brightness and darkness, and even if incoming panel does not have Mura at all, after the incoming panel is assembled into a liquid crystal display device by matching with BLU with poor brightness uniformity in the television manufacturers, the display effect is still affected by the BLU to generate Mura, so the television manufacturers also need to perform Mura repair on the assembled liquid crystal display device with poor display effect; because the original Mura compensation data of the panel is stored in a fixed position in the flash by a panel manufacturer, if the television manufacturer performs Mura repair again, the brightness difference of the BLU is converted into the Mura compensation data, and the Mura compensation data is covered and stored in the same position in the flash, so that the original Mura compensation data of the panel is lost.
