Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
fig. 1 is a sub-pixel schematic diagram of a pixel display method for improving the burn-in performance according to the present invention. Compared with the conventional sub-pixels, each RGB sub-pixel is divided into 2 sub-pixels according to the area, and each sub-pixel can independently control the switch and the brightness.
Fig. 2 shows an LCD display method for improving burning performance according to the present invention, which specifically includes the following steps:
the method comprises the following steps that firstly, a detection and judgment module monitors input display signals, and when the situation that the display signals input in a certain area do not change for a long time is monitored, a protection display mode is judged to be entered under the situation;
after entering a protection display mode, each secondary sub-pixel performs dynamic display according to a set rule to prevent each sub-pixel from being in a certain fixed brightness display state for a long time, so that the problem of LCD image residue caused by long-term lighting is solved;
step three, the detection and judgment module keeps monitoring the input display signal, and returns to the normal display mode when the area signal changes;
and step four, in the normal display mode, each secondary sub-pixel displays according to the conventional brightness.
The brightness is the ratio of the luminous intensity of the luminous body to the area of the light source, and is defined as the brightness of the light source unit, namely the luminous intensity of the unit projection area. Under the protection display mode, the dynamic display of the secondary sub-pixel is characterized by brightness differentiation, and the regular design follows the principle of consistent brightness, and specifically comprises the following steps: all sub-pixel luminance combinations within each sub-pixel are scaled to the luminance of the entire sub-pixel.
FIG. 3 shows a liquid crystal arrangement of a brightness level S1; fig. 4 shows the liquid crystal alignment for a brightness level S2. Where the sub-pixel luminance S0= S1+ S2 of fig. 1. And setting a rule for protecting the dynamic display of the secondary sub-pixels in the display mode aiming at the brightness level of each sub-pixel. The dynamic display rule of the sub-pixel region 1 in fig. 1 is S1 → S2 → S1 → S2 … …, and the dynamic display rule of the sub-pixel region 2 in fig. 1 is S2 → S1 → S2 → S1 … …, and this is taken as a loop. When a long-time holding of a screen is required, a certain relationship is set and display is performed alternately and dynamically, and each sub-pixel is not in a high-luminance light-emitting state for a long time. Thus, image sticking caused by long-term lighting can be prevented to a great extent.
Two sub-pixel brightness combinations are set for the protection display mode of each grade, and the change period is set to be 1 s. The two regions of RGB sub-pixels will switch between S1 and S2 at a frequency of once per second until the protected display mode is exited.
The change rule of the sub-pixel brightness provided by the present invention is not unique, and can be designed differently according to actual requirements, and the above examples are used for explaining and explaining the display method provided by the present invention for understanding, but are not intended to limit the content of the present invention.
Example two:
fig. 5 is a schematic diagram of RGB sub-pixels of the pixel display method for improving the burning performance according to the present invention. Compared with the traditional RGB pixel, each sub-pixel is equally divided into 2 sub-pixels according to the area, and each sub-pixel can independently control the switch and the brightness.
Unlike the first embodiment, the present embodiment subdivides each RGB sub-pixel. This embodiment is intended to illustrate that the subdivision of the RGB sub-pixels may or may not be uniform.
The invention relates to a pixel display method for improving burning performance. The invention can be used for the LCD display panel
In summary, compared with the prior art, the invention is used for improving the burning attaching performance of the LCD panel and is beneficial to passing the burning attaching performance test. The RGB sub-pixels are subdivided into two or more areas in the liquid crystal layer, and each liquid crystal switch can independently control the switch; setting a detection and judgment module, and automatically entering a protection display mode when detecting that a display picture is kept unchanged within a certain time; under the protection display mode, different liquid crystal areas of the RGB sub-pixels carry out alternate chromaticity change, so that the image sticking probability is reduced, and the panel burning performance is improved. The invention solves the problem of image residue of the LCD panel by using RGB pixel arrangement, and ensures the maximization of the display effect and the service life.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
