Background

In the development of panel display technology, for example, UHD (3840x 2160) high-resolution liquid crystal display panels are widely used in the television display market, but for panel manufacturers, UHD-standard products are not profitable, and due to the widespread availability of panel manufacturers, the prices in the market are in the low-price competition and are thin and profitable. In a conventional UHD panel architecture, H-direction scan lines are controlled by a GOA circuit in glass, V-direction data lines are controlled by a driver IC, the total number of V-direction data lines is 11520(3840 × 3), and taking a driver IC of a common 960channel specification as an example, 12 panels are required in total.

Based on the market demand for cost reduction, low-cost architectures with lower resolution, such as HD and FHD, are also gradually applied to UHD-compliant panels, and common architectures, such as Triple-Gate and Dual-Gate, are mainly used to reduce the number of driving ICs on each panel.

Generally, a UHD panel under the framework of V-stripe RGB or H-stripe RGB is matched with a digital low color cast technology, and a digital low color cast 8-Domain display technology in the market utilizes four sub-pixels to combine into a new 8-Domain pixel display unit on the basis of a TFT-LCD design of 4 domains; two of the High regions and two of the Low regions improve the problem of Low color cast in side view in a mode of reducing resolution, and the High regions and the L pixel regions have the following characteristics:

(1) the area ratio of the High region to the Low region is 1: 1; (2) high region: gamma curve low gray scale brightness is brighter; (3) low region: gamma curve low gray scale is darker.

At present, the mainstream digital low-color cast technology is carried out based on a V-stripe RGB or H-stripe RGB architecture, and other special architectures are not applicable, so that driving interference and inappropriate lines are generated; the present invention provides a special display structure and a digital low color shift design suitable for the structure. FIG. 1 shows a digital low color shift driving scheme of a conventional architecture (V stripe), in which H + is a positive voltage of high gray scale, H-is a negative voltage of high gray scale, L + is a positive voltage of low gray scale, and L-is a negative voltage of low gray scale, the concept of which is shown in the meaning diagram of 4 gray scale voltages in FIG. 2. The same number of H regions and L regions are available in both horizontal and vertical directions, and the polarity arrangement is a sequential arrangement of two positive (+) and two negative (-), but this driving is only suitable for the low color shift technique of the conventional (V stripe) architecture. Therefore, the present application provides a special display architecture and a digital low color shift design suitable for the architecture.

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 invention provides a novel panel framework, and the RGB sub-pixel arrangement rule is as follows: the three sub-pixels are randomly arranged in the transverse direction and the longitudinal direction to form basic units with different colors; wherein the three sub-pixels of any two adjacent basic units are arranged in different orders.

Further, in one specific form, the sub-pixels are composed of R, G, B basic units with different colors in the V direction, and are repeatedly arranged along the V direction; the three sub-pixels have 6 arrangement sequences, after the initial arrangement sequence is fixed, all the sub-pixels are repeatedly arranged according to the fixed sequence; the Normal architecture is usually the same color in the column direction.

Furthermore, in one embodiment, the pixel position of each row is shifted up or down by one sub-pixel with respect to the previous row, and each next row is fixed to move in the same direction; the Normal architecture has no displacement, and the RGB Pen-tile architecture does not conform to the rule.

Further, in a specific form, in a 2X3 or 3X2 rectangular region formed by any 6 adjacent pixel units, two R, two G, and two B pixels are bound to form, and the same color is not adjacent, 2 groups of color diagonals are adjacent, and there is a group of color diagonals that are also not adjacent. The RGB Pen-tile architecture does not comply with this rule

Further, in one specific form, the pixel is composed of R, G, B basic units with three different colors in the V direction, and is repeatedly arranged along the V direction; the three sub-pixels have 6 arrangement sequences, after the initial arrangement sequence is fixed, all the sub-pixels are repeatedly arranged according to the fixed sequence; the pixel position of each row is shifted upwards or downwards by one sub-pixel relative to the previous row, and each next row is fixed to move towards the same direction; and satisfy, in the 2X3 or 3X2 rectangular region that arbitrary 6 adjacent pixel units constitute, certainly constitute by two R, two G, two B pixels, and the looks is not adjacent, has 2 groups of color diagonals to be adjacent, has a group of color diagonal neither to be adjacent. As shown in fig. 3, any 6 pixels in the figure have the same number of R, G, B for 3 regular arrangements.

Taking the conventional UHD architecture as an example, the arrangement of 3840RGB (x3) x2160(x1) of the conventional UHD architecture is converted into "3840 (x2) x2160(x1.5) resolution + special RGB arrangement", or 2560(x3) x3240(x1) resolution, that is, the total number of H-direction pixels is increased to 1.5 times of the original one, and the total number of V-direction pixels is decreased to 2/3.

In this arrangement, if the driver IC selects 960ch, the number of ICs is 9; if the driver IC selects 1280ch, the number of ICs is 6.

The structure can save the number of ICs, and the panel transmittance can also maintain the same level as that of the general UHD structure, FIG. 4 is a comparison graph of the pixel position relationship between the conventional structure and the novel structure provided by the present embodiment, the left side is the conventional structure, and the right side is the novel structure provided by the present embodiment.

Based on the same inventive concept, in addition to the above-mentioned new panel architecture, two digital low color shift driving techniques suitable for this architecture are also proposed in the embodiments.

Fig. 5 shows a first low color shift driving method (column + -polarity arrangement with H flip HL in the horizontal direction) of this embodiment, in which H regions and L regions are arranged in a manner that the row direction has the same H or L regions, the column direction is H and L are staggered, and in the polarity arrangement, the row direction is sequentially arranged in a positive (+) direction and a negative (-) direction, and the column direction is sequentially arranged in a fully positive (+) or fully negative (-) direction.

Fig. 6 shows a second low color shift driving method (column + - + polarity matched column HLHL arrangement) of this embodiment, in which the H region and the L region are arranged in such a way that the column direction has the same H orL region, the row direction is H and L staggered, and in the polarity arrangement, the column direction is all positive (+) or all negative (-) sequentially, the row direction is initially arranged as a single all + or all-, the second column must have different polarities, the third column and the second column have the same polarity, and the next polarity is either two positive (+) two negative (-) or two negative (-) two positive (+) sequentially. With frame switching, the whole frame pixel polarity needs to be reversed.

The above two combinations are special and unique driving combination modes, and the following advantages can be completely met: the driving chip has low temperature and low power consumption (column polarity inversion), the image transmission speed of the driving chip can still use the design with lower manufacture procedure, low area and low cost, the color cast problem of the panel when being watched at a large visual angle is improved, and meanwhile, the driving interference and the improper texture generation do not exist.

While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the invention.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
