Shared pixel circuits
The invention discloses an optoelectronic system may include an array of pixel circuits connected to optoelectronic devices. There can be different types of optoelectronic devices (for example, red, green and blue). These devices can be sensors, or light emitting devices or other types of devices. These devices may be optimized differently and to program the pixel circuits, a configuration of dataline for columns and address lines for rows is used.
1 . A method to separate two consecutive frames, the method comprising:
connecting pixel circuits and optoelectronic devices in an array of columns and rows; and
sharing the pixel circuits between more than one optoelectronic devices and turning ON each optoelectronic device through a pixel circuit during a period of a frame wherein there is a black matrix at the end of the frame,
wherein more than one dataline is used to program one column and different groups of pixel circuits in the column are connected to a different dataline.
2 . The method of claim 1 , wherein the two consecutive frames separate resulting in less color shifts.
3 . The method of claim 1 , wherein the pixel circuits are optimized differently for each device wherein a current bias level is different.
4 . The method of claim 3 , wherein there are optimized pixel circuits for each optoelectronic device type wherein the optimized pixel circuit is shared with a same type of adjacent optoelectronic devices.
5 . The method of claim 3 , wherein to program the pixel circuits, a configuration of dataline for columns and address lines for rows is used and least one control or address line for a row is activated and the data from the dataline is programmed into the pixel or the data from the pixel is transferred into the dataline.
6 . The method of claim 5 , wherein after programming one row, the address/control line is deactivated, and the next row is activated.
7 . The method of claim 3 , wherein all rows are programmed during each frame or a period of time.
8 . The method of claim 3 , wherein as the pixels need to be reprogrammed several times during each frame time, multiple data lines are used for each column to program multiple pixels in each column, wherein further, the address/control line for more than one row is activated while different datalines are connected to the pixels in each row.
9 . The method of claim 1 , wherein at least for two adjacent pixels, different optoelectronic devices are turned ON during a period of the frame time.
10 . The method of claim 1 , wherein the pixel circuits are shared between similar types of optoelectronic devices from adjacent pixels.
11 . The method of claim 1 , wherein at least two pixels in the columns are programmed at the same time.
12 . The method of claim 1 , wherein the pixel circuit is shared between the optoelectronic devices in a same pixel wherein the pixel circuit is time shared between different devices.
13 . The method of claim 1 , wherein during a first part of the frame it is connected to a first optoelectronic device in the pixel, during a second part of the frame the pixel circuit is controlling a second type of optoelectronic device and during a third part of the frame time, the pixel circuit is controlling a third optoelectronic device.
14 . The method of claim 1 , wherein two adjacent pixels do not activate a same device during a period of the frame.
15 . The method of claim 1 , wherein the pixels in the columns are set into different groups such that a different dataline is connected to each group and wherein during programming an address/control line from each group is activated as a result one row from each group is activated to get programmed.
16 . The method of claim 15 , wherein the column is divided into several consecutive sections matching the number of datalines.
17 . The method of claim 15 , wherein no two adjacent pixels are allocated to the same group.
18 . The method of claim 15 , wherein a set of adjacent pixels are allocated to one group with this pattern repeated across the column.
19 . The method of claim 15 , wherein the control lines are used as row lines to connect the pixel to different optoelectronic devices wherein the control lines are shared between rows in one group type and wherein a front plane is used to increase the resolution of the said optoelectronic system here.
20 . The method of claim 19 , wherein the front plane is a liquid crystal or MEMS type wherein the front plane is synchronized with the pixels.
21 . The method of claim 19 , wherein the optoelectronic system is a display, a full color image is enabled on the optoelectronic system and the front plane has a color filter showing the higher resolution image.
