Description

An AMOLED (Active-matrix organic light emitting diode) panel usually adopts a Sub Pixel Rendering (SPR) technique to increase the PPI (Pixels per inch). The most typical pixel arrangement using SPR techniques is RGBG, another pixel arrangement is Delta-RGB. Using the technique of SPR, 1/3 sub-pixels can be saved at the same PPI.

Due to the limitation of factors such as wiring space, line width (wiring resistance), Thin Film Transistor (TFT) driving capability and electric leakage, the driving capability of the CELL test circuit can reach a bottleneck. If the driving performance is low, when a monochrome picture is displayed, sub-pixels of other colors may still be in a weak light emitting state, or the picture brightness is not uniform due to the wiring resistance, which affects the judgment of quality inspection and causes the light emitting display effect to be poor.

Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention 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.
For example, a display device includes: the backlight module comprises a back panel circuit, a plurality of electroluminescent devices and a plurality of data lines; the electroluminescent device comprises a plurality of sub-pixels with different colors, the colors of the sub-pixels are three, the sub-pixels are sequentially and repeatedly arranged according to the three colors, the sub-pixels are arranged in multiple rows, the backboard circuit comprises a plurality of circuit units, and each sub-pixel is connected with one circuit unit; the number of the data lines is at least one more than that of the rows of the sub-pixels, each data line is connected with a plurality of circuit units, and the sub-pixels with the same color in two adjacent rows are connected with one data line through the corresponding circuit units.
In the above embodiment, the voltage is provided to the sub-pixels of the same color through one data line, so that the voltage of the data line is kept stable without switching, and further, the sub-pixels can obtain stable voltage, thereby obtaining better light-emitting display effect.
In one embodiment, as shown in fig. 1 and 2, a display device 10 includes: a backplane circuit 100, a plurality of electroluminescent devices 200, and a plurality of data lines 300; the electroluminescent device 200 includes a plurality of sub-pixels 210 with different colors, the color of each sub-pixel 210 is three, the sub-pixels 210 are sequentially and repeatedly arranged according to the three colors, each sub-pixel 210 is arranged in multiple rows, the backplane circuit 100 includes a plurality of circuit units 110, and each sub-pixel 210 is connected with one circuit unit 110; the number of the data lines 300 is at least one more than the number of the rows of the sub-pixels 210, each data line 300 is connected to a plurality of the circuit units 110, and the sub-pixels with the same color in two adjacent rows are connected to one data line through the corresponding circuit unit.
Specifically, the backplane circuit is an LTPS (Low Temperature polysilicon) backplane circuit, which is used to drive the electroluminescent device, and in this embodiment, the electroluminescent device is an Organic electroluminescent device, for example, an OLED (Organic Light-Emitting Diode) device, the organic electroluminescent device comprises an anode, an organic luminescent layer, a cathode and other components, and the organic luminescent layer with different colors is formed to ensure that the organic electroluminescent device can emit light to display different colors, for example, the emission colors of the plurality of organic electroluminescent devices are red, green and blue, respectively, that is R, G and B, it will be appreciated that each organic electroluminescent device constitutes a sub-pixel, and thus the organic electroluminescent device comprises sub-pixels of the three colors R, G and B.
The data lines are column signal lines, or data lines. When the display device is applied to LCD display, the data line is used as a column signal line of the TFT, connected to a source of the TFT, and thus, may also be referred to as a source line. The data line is used to supply a data voltage to the organic light emitting device.
The circuit unit is a pixel driving circuit unit, also called a pixel circuit, and is used for driving the sub-pixels to emit light, or the organic electroluminescent device to emit light. The data line inputs a data voltage to the circuit unit, thereby causing the circuit unit to output a driving current to the organic electroluminescent device. In order to make each sub-pixel capable of emitting light, each sub-pixel is connected with a circuit unit, and each sub-pixel is connected with a data line through the circuit unit.
In this embodiment, each organic electroluminescent device is arranged in a rectangular array, for example, as shown in fig. 1, each of the sub-pixels is arranged in a rectangular array, that is, each of the sub-pixels is arranged in a rectangular array of rows and columns, for example, the display device in this embodiment is an active matrix organic light emitting display device. In this embodiment, the sub-pixels are arranged repeatedly in R, G and B colors, that is, the sub-pixels in each row are arranged repeatedly in R, G and B. For example, the number of sub-pixels of each color is equal, i.e., the number of sub-pixels of any one color is the same as the number of sub-pixels of another color. Therefore, the sub-pixels of various colors of the display device are uniformly distributed, and the display effect is better.
In this embodiment, a Delta-RGB pixel arrangement structure is further described, and in this embodiment, the sub-pixels of the same color in two adjacent rows are staggered. For example, the sub-pixels in the odd-numbered rows are arranged in the same manner, the sub-pixels in the even-numbered rows are arranged in the same manner, the sub-pixels in the odd-numbered rows are arranged in the different manner, and the sub-pixels in the odd-numbered rows and the sub-pixels in the even-numbered rows have the same color, and for example, the sub-pixels in the odd-numbered rows are arranged in the RGB order, and the sub-pixels in the even-numbered rows are arranged in the BRG order, so that the sub-pixels in each column have two color types, that is, the sub-pixels in each column have two color types, and the sub-pixels in two adjacent columns have three color types, that is, each column necessarily includes one of the sub-pixels in the RGB color.
In this way, the sub-pixels with the same color in two adjacent columns can be connected to the same data line, that is, the sub-pixels with the same color in two adjacent columns are connected to the same data line through the circuit units respectively connected with the sub-pixels. That is to say, the sub-pixels of the same color in two adjacent columns are connected to the same data line through the corresponding circuit units, which is equivalent to that the sub-pixels in each column are respectively connected to one data line in a staggered manner, so that the sub-pixels of the same color are connected to one data line, and the arrangement of the sub-pixels is still arranged according to the Delta-RGB pixel arrangement structure, and is not staggered. In this embodiment, the number of the data lines is one more than the number of the columns of the sub-pixels, that is, the number of the data lines is the number of the columns of the sub-pixels plus one, so that the sub-pixels of the same color in each two columns can be respectively connected to the data lines, and the driving of each sub-pixel is realized. Therefore, voltage is provided for the sub-pixels with the same color through one data line, the voltage of the data line does not need to be switched and keeps stable, the sub-pixels can obtain stable voltage, and the light-emitting display effect is better.
Specifically, the data voltage of the data line can determine the current provided by the circuit unit to the OLED, for example, the lower the data voltage, the higher the current of the OLED, the higher the brightness; the higher the data voltage, the smaller the OLED current, and the lower the brightness.
As shown in fig. 3, in the conventional display device, two color sub-pixels are controlled by one data line, and the driving voltage waveform in the RGB monochrome picture corresponds to the curve shown by Vsource1, because the data voltages in the odd-numbered rows and the even-numbered rows are different, the data voltage needs to be switched for driving the sub-pixels in different rows, for example, the voltage needs to be switched from High (High level) to Low (Low level) or from Low (Low level) to High (High level), that is, the voltage needs to be switched once for driving one row by the data line. Since the data line and the signal line of the daughter board test both have parasitic capacitance and routing resistance, so that the output of the data voltage has RC delay, and therefore, the actually measured waveform has a corresponding curve as shown in Vsource2, the RC delay exists when the data voltage is switched, the higher the resolution (the shorter the 1 line time is), the larger the parasitic RC (the larger the time constant is), and the smaller the TFT on current (Ion) of the CELL test is, the more serious the waveform distortion corresponding to the data voltage of the data line will be, and finally, the Low voltage in the Low output state is not Low, and the High voltage in the High output state is not High enough, so that in displaying an RGB monochrome picture, the picture brightness is not High enough, and other sub-pixels which do not emit light can emit light weakly, so that the display effect is not good.
In the embodiment, one data line only controls one color of sub-pixels, so that the data voltage of the data line is a dc voltage, the waveform of the data voltage is a corresponding curve as shown in Vsource3, and the data voltage does not need to be switched, and therefore, the data voltage is not affected by RC delay.
In order to enable each sub-pixel to be connected to a data line through a corresponding circuit unit, in one embodiment, as shown in fig. 1, each circuit unit is arranged in multiple columns, where one PXL in the figure is a circuit unit, for example, each circuit unit is arranged in multiple rows and multiple columns, for example, each circuit unit is arranged in a rectangular array of multiple rows and multiple columns, for example, the number of columns of the circuit unit is at least one more than the number of columns of the sub-pixels, for example, the number of columns of the circuit unit is the same as the number of the data lines, for example, the number of the circuit unit is more than the number of the sub-pixels, in this embodiment, each circuit unit is arranged in multiple columns, and the circuit unit is more than the sub-pixel by one column, so that each sub-pixel can be connected to one data line through one circuit unit, and the sub-pixels of the same color in two adjacent columns can be connected to the same data line through the circuit unit, thereby realizing the drive of one data line to the sub-pixels of the same color.
In this embodiment, since the number of the data lines is one more than the number of the columns of the sub-pixels, the sub-pixels of two colors in each column are respectively connected to two data lines, that is, the sub-pixel of one color in one column is connected to one data line, and the sub-pixel of another color in the one column is connected to the other data line, so that each color in each column can be connected to the data line.
For example, the sub-pixels of two colors in the same column are sequentially arranged at intervals, that is, the sub-pixels of two colors in the same column are alternately arranged and are mutually spaced, for example, the sub-pixel color in the first column includes R and B, then in this column, the RB pixels are arranged as rbrb … …, and R and B are alternately arranged and are mutually spaced, so that the pixel distribution is more uniform, and the light emitting effect is better. And the sub-pixels of the second column adjacent to the first column comprise GR, in this column, GR pixels are arranged in GRGRGR … …, G and R alternate and are arranged at intervals, the sub-pixels of the third column adjacent to the second column comprise BG, BG pixels are arranged in BGBGBG … …, B and G alternate and are arranged at intervals.
Please refer to fig. 1 and fig. 2, wherein fig. 2 is a schematic diagram of the connection between the sub-pixels and the data lines, such that the B sub-pixels in the first column are connected to the data line S1, the R sub-pixels in the first column are connected to the R sub-pixels in the second column and the data line S2, the G sub-pixels in the second column and the G sub-pixels in the third column are connected to the data line S3, that is, each data line is connected to the sub-pixels of the same color in two adjacent columns, such that the number of the data lines is one more than the number of the columns of the sub-pixels, such that each sub-pixel can be connected to the data line, and such that the data line is connected to the sub-pixels of the same color, which is beneficial for better light emitting display effect.
In order to connect the sub-pixels of the same color to the same data line, in the above embodiment, the sub-pixels of the same color in two adjacent columns of sub-pixels are connected to the same data line through the corresponding circuit units, that is, the circuit units in two adjacent columns are connected to three data lines respectively while being staggered with each other, that is, the circuit units are not staggered in arrangement but only staggered with the data line, so that the sub-pixels of the same color in two adjacent columns can be connected to the same data line.
In order to facilitate the processing, for example, at least some of the circuit units in the two outer columns are not connected to the sub-pixels, it should be understood that, since the two colors of the sub-pixels in each column are respectively connected to two data lines, so that the sub-pixels of the same color in the two adjacent columns can be connected to one data line, and for the sub-pixel in the outer column, the sub-pixel of one color is not connected to the sub-pixel of the same color in the adjacent column, so that the sub-pixel of the color in the column is connected to one data line alone, for example, in fig. 2, the B sub-pixel in the first column is connected to the data line S1 alone, but does not share one data line with the B sub-pixels in the other columns, so that for the circuit unit in the first column, there is a circuit unit which is not connected to the sub-pixel, for example, the B sub-pixels in the last column are individually connected to the data line S7, and for the circuit units in the last column, there are circuit units that are not connected to the sub-pixels, so that, as shown in fig. 1, a Dummy structure, that is, a Dummy unit, may be disposed in the backplane circuit 100 at a portion that is not connected to the sub-pixels 210, so that the circuit units of the backplane circuit can have a rectangular array structure, and the number of columns of the circuit units is one more than that of the sub-pixels, so that each sub-pixel can be connected to the data line.
It should be noted that, the data line and the circuit unit, and the connection between the circuit unit and the OLED can be implemented by using the prior art, for example, as shown in fig. 4, the circuit unit includes a first switch transistor T1, a second switch transistor T2 and a capacitor C, the data line source is connected to the source of the first switch transistor T1, the scan line scan is connected to the gate of the first switch transistor T1, the drain of the first switch transistor T1 is connected to the gate of the second switch transistor T2, the first power VDD is connected to the source of the second switch transistor T2, the first power VDD is connected to the gate of the second switch transistor T2 through the capacitor C, the drain of the second switch transistor T2 is connected to the anode of the OLED, and the cathode of the OLED is connected to the second power VSS, so that the data voltage signal is input to the data line of the first switch transistor T1, the scan line scan signal is input to turn on the first switch transistor T1, and then the second switch transistor T2 is turned on after receiving the scan signal, the OLED is turned on, thereby realizing light emission.
In the above embodiments, the voltage is provided to the sub-pixels of the same color through one data line, so that the voltage of the data line is kept stable without switching, and further, the sub-pixels can obtain stable voltage, thereby obtaining better light-emitting display effect.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
