To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The liquid crystal display panel overdrive method provided by the application can be applied to the application environment shown in fig. 1. Among them, the liquid crystal display panel may include a driving device 110 and a light emitting device 120. The driving device 110 is connected with the light emitting device 120, wherein the driving device 110 may include a driving chip; the driving chip may be, but not limited to, a single chip or a DSP (Digital signal processing). The light emitting device 120 may be, but is not limited to, an LCD light emitting device and an LED light emitting device.
As shown in fig. 2, the lcd panel can be divided into a mask splicing region (B region) and a non-splicing region (a region).
In one embodiment, as shown in fig. 3, there is provided an overdrive method of a liquid crystal display panel, which is exemplified by the method applied to the driving apparatus in fig. 1, and the method includes the following steps:
step S310, a first overdrive reference table corresponding to a splicing area and a second overdrive reference table corresponding to a non-splicing area are obtained; the splicing area and the non-splicing area are obtained by dividing the liquid crystal display panel.
The splicing area refers to an area where a CF (color filter) mask is spliced in the liquid crystal display panel. The non-tiled region refers to a region of the liquid crystal display panel other than the tiled region. In one example, the tiled area and the non-tiled area in combination constitute an overall display area of the liquid crystal display panel. The first overdrive reference table has different overdrive values; each overdrive value stored in the first overdrive reference table corresponds to each first weight value one by one. The second overdrive reference table has a different overdrive value; and each overdrive value stored in the second overdrive reference table corresponds to each second weight value one by one.
Specifically, based on dividing the display device into a splicing region and a non-splicing region, the driving device may further obtain a first overdrive reference table corresponding to the splicing region and a second overdrive reference table corresponding to the non-splicing region.
In one example, the first overdrive reference table and the second overdrive reference table may be stored in a register in advance, and the driving device may further obtain the first overdrive reference table corresponding to the splicing area and the second overdrive reference table corresponding to the non-splicing area through the register.
In one example, the non-stitched regions are located on both sides of the stitched region.
Step S320, acquiring first weight values of different gray scales corresponding to each first subregion; performing overdrive processing on corresponding first sub-regions according to the first weights and the first overdrive reference table to obtain first adjustment weight value data; the first sub-region is obtained by equally dividing the splicing region.
The splicing area can be equally divided according to a preset dividing size to obtain each first sub-area. For example, the splicing region may be equally divided into 8 first sub-regions. The first weight value refers to the weight value of the corresponding gray scale of the first sub-region. In one example, the first sub-region may include several sub-pixels. The weight of the corresponding gray scale in the first sub-region can be determined according to the size of the first sub-region, the number of sub-pixels included in the first sub-region, and the gray scale. The first adjustment weight value data refers to weight value data after the over-drive adjustment is performed on the first sub-region.
Specifically, each first sub-region can be obtained by equally dividing the splicing region. The driving device can obtain first weights corresponding to different gray scales of each first sub-region, and perform overdrive processing on the corresponding first sub-regions according to each first weight and the first overdrive reference table, so as to obtain first adjustment weight value data.
It should be noted that the first weight preset is stored in the register, and the driving device may obtain the corresponding first weight through the register.
Step S330, acquiring second weight values of different gray scales corresponding to each second subregion; performing overdrive processing on the corresponding second sub-areas according to the second weights and the second overdrive reference table respectively; obtaining second adjustment weight value data; the second sub-area is obtained by equally dividing the non-splicing area; the first adjustment weight value data is the same as the second adjustment weight value data.
And equally dividing the non-splicing area according to the preset division size to obtain each second sub-area. For example, the non-spliced region may be equally divided into 16 second sub-regions. The second weight refers to the weight of the corresponding gray scale in the second sub-region. In one example, the second sub-region may include several sub-pixels. The weight of the corresponding gray scale in the second sub-region can be determined according to the size of the second sub-region, the number of sub-pixels included in the second sub-region, and the gray scale. The second adjustment weight value data refers to weight value data after the second sub-region is subjected to over-drive adjustment.
Specifically, each second sub-region can be obtained based on equal division of the non-spliced region. The driving device can obtain second weights corresponding to different gray scales of each second subregion, and perform overdrive processing on the corresponding second subregions according to each second weight and the second overdrive reference table, so as to obtain second adjustment weight value data, and the second adjustment weight value data is equal to the first adjustment weight value data.
It should be noted that the preset second weight is stored in the register, and the driving device may obtain the corresponding second weight through the register.
In the embodiment of the overdrive method for the liquid crystal display panel, a first overdrive reference table corresponding to the splicing area and a second overdrive reference table corresponding to the non-splicing area are obtained; the splicing area and the non-splicing area are obtained by dividing the liquid crystal display panel; acquiring first weights of different gray scales corresponding to the first sub-areas; performing overdrive processing on corresponding first sub-regions according to the first weights and the first overdrive reference table to obtain first adjustment weight value data; the first sub-area is obtained by equally dividing the splicing area; acquiring second weights of different gray scales corresponding to the second subregions; performing overdrive processing on the corresponding second sub-areas according to the second weights and the second overdrive reference table respectively; obtaining second adjustment weight value data; the second sub-area is obtained by equally dividing the non-splicing area; the first adjustment weight value data is the same as the second adjustment weight value data. The weights of the same gray scales of the non-splicing area and the splicing area are the same, namely the brightness of the same gray scales of the non-splicing area and the splicing area is the same, so that the color shift tailing phenomenon caused by the color resistance width difference of the splicing area due to the CF light shield splicing is counteracted, and the display effect of the liquid crystal display panel is improved.
In one embodiment, as shown in fig. 4, there is provided a liquid crystal display panel overdrive method, which is exemplified by the application of the method to the driving apparatus in fig. 1, and the method includes the following steps:
step S410, based on CF (Color Filter) light mask splicing, divides the liquid crystal display panel into a splicing area and a non-splicing area.
Specifically, the liquid crystal display panel may be divided into 2 regions according to whether CF photomasks are spliced, wherein the region where the CF photomasks are spliced is divided into a spliced region; the area without CF photomask splicing is divided into non-splicing areas.
In one example, the liquid crystal display panel may include a tiled area where 1 or more CF light shades are tiled.
Step S420, a first overdrive reference table corresponding to the splicing area and a second overdrive reference table corresponding to the non-splicing area are obtained; the splicing area and the non-splicing area are obtained by dividing the liquid crystal display panel.
Step S430, acquiring first weight values of different gray scales corresponding to each first subregion; performing overdrive processing on corresponding first sub-regions according to the first weights and the first overdrive reference table to obtain first adjustment weight value data; the first sub-region is obtained by equally dividing the splicing region.
Step S440, acquiring second weight values of different gray scales corresponding to each second subregion; performing overdrive processing on the corresponding second sub-areas according to the second weights and the second overdrive reference table respectively; obtaining second adjustment weight value data; the second sub-area is obtained by equally dividing the non-splicing area; the first adjustment weight value data is the same as the second adjustment weight value data.
The specific content processes of step S420, step S430 and step S440 may refer to the above contents, and are not described herein again.
Because the width of the red resistor, the width of the green resistor and the width of the blue resistor in the splicing area spliced by the CF photomask are different (and the width of the red resistor and the width of the green resistor are different from those of the blue resistor in the splicing area respectively), namely the widths of the corresponding color resistors are different, the passing light is also different under the same gray scale, and thus the trailing color cast can be caused.
In the application, the liquid crystal display panel can be divided into a splicing area and a non-splicing area based on CF photomask splicing, and a first overdrive reference table corresponding to the splicing area and a second overdrive reference table corresponding to the non-splicing area are obtained; acquiring first weights of different gray scales corresponding to the first sub-areas; performing overdrive processing on corresponding first sub-regions according to the first weights and the first overdrive reference table to obtain first adjustment weight value data; acquiring second weights of different gray scales corresponding to the second subregions; performing overdrive processing on the corresponding second sub-areas according to the second weights and the second overdrive reference table respectively; and obtaining second adjustment weight value data, wherein the first adjustment weight value data and the second adjustment weight value data are the same, and further the weights of the same gray scales of the non-splicing area and the splicing area are the same, namely the brightness of the same gray scales of the non-splicing area and the splicing area is the same, so that the color shift tailing phenomenon caused by the color resistance width difference of the splicing area due to the splicing of the CF light shield is counteracted, and the display effect of the liquid crystal display panel is improved.
In the above embodiment, the liquid crystal display panel is divided into 2 regions (the splicing region and the non-splicing region) based on whether the CF photomasks are spliced, and overdrive is adjusted for the 2 regions respectively by referring to the corresponding overdrive reference tables, so that weights of the same gray scales of the non-splicing region and the splicing region are the same, that is, the brightness of the same gray scale of the non-splicing region and the splicing region is the same. And aiming at the CF photomask splicing area, the overdrive in the overdrive reference table is changed to adjust the overdrive so as to offset the color shift tailing caused by the color resistance width difference caused by CF photomask splicing.
In one embodiment, as shown in fig. 5, a processing step of the first weight is provided, and the method of the step is exemplified by being applied to the driving apparatus in fig. 1. The step of obtaining the first weight of each first sub-region corresponding to different gray scales comprises:
step S510, obtaining a region weight of each first sub-region.
Wherein, the region weight of the first sub-region refers to the weight of the first sub-region. In one example, the first sub-region may include several sub-pixels. The weight of the first sub-region can be determined according to the size of the first sub-region and the number of sub-pixels included in the first sub-region.
Specifically, the area weight corresponding to the first sub-area may be stored in a register in advance, and the driving device may obtain the area weight of each first sub-area through the register.
In step S520, the area weight of each first sub-area and the preset gray scale weight corresponding to different gray scales are multiplied to obtain each first weight.
Wherein, different gray scales correspond to different preset gray scale weights.
Specifically, the driving device may perform multiplication processing on the obtained area weight of the first sub-area and the preset gray scale weight corresponding to the corresponding gray scale, and then may obtain the corresponding first weight, so that the driving device may perform overdrive processing on the corresponding first sub-area according to the first weight and the first overdrive reference table, thereby implementing adjustment of overdrive of the spliced area, so as to offset color shift trailing caused by a color resistance width difference due to CF photomask splicing.
In one embodiment, as shown in fig. 6, a processing step of the second weight is provided, and the method of this step is exemplified by being applied to the driving apparatus in fig. 1.

Wherein the region weight of the second sub-region refers to the weight of the second sub-region. In one example, the second sub-region may include several sub-pixels.

Specifically, the area weight corresponding to the second sub-area may be stored in a register in advance, and the driving device may obtain the area weight of each second sub-area through the register.
Step S620, performing product processing on the area weight of each second sub-area and the preset gray scale weight corresponding to different gray scales to obtain each second weight.
Wherein, different gray scales correspond to different preset gray scale weights.
Specifically, the driving device may perform multiplication processing on the obtained region weight of the second sub-region and the preset gray scale weight corresponding to the corresponding gray scale, and then may obtain the corresponding second weight, so that the driving device may perform overdrive processing on the corresponding second sub-region according to the second weight and the second overdrive reference table, thereby implementing overdrive adjustment of the spliced region, so that the brightness of the same gray scale of the non-spliced region and the spliced region is the same, so as to cancel color shift tailing caused by a color resistance width difference due to CF photomask splicing, and improve the display effect of the liquid crystal display panel.
