Description

Electronic device

This disclosure relates to an electronic device, particularly an electronic device having two screens (displays) that can be spliced.

In modern society, notebook computers have been widely used, and with the development of notebook computers, various designs of notebook computers have been produced. In order to have more operation screens or display screens, some notebook computers have dual screens. For example, in addition to the original screen of the laptop, the touch area on the base surface of the laptop is designed as another additional screen, or the entire base surface of the laptop is designed as another additional screen.

However, this extra screen does not blend well with the original screen. Specifically, the original screen is usually located on the inside of the top cover of the laptop (usually referred to as the B-piece), and the additional screen is located on the surface of the base of the laptop (usually referred to as the C-piece). The shafts are separated. Therefore, the extra screen and the original screen still appear to be separate screens.

In addition, when a part of the image displayed on the original screen is extended and displayed on the additional screen, the brightness and color of the image on the two screens may be inconsistent due to the color difference between the two screens. Therefore, there is a need for improvements on notebook computers with dual screens to address these issues.

The disclosure provides an electronic device. The electronic device includes a first display, at least one first support, a second display, at least one second support, a processor, and a display card. The first bracket is rotatably connected to a side edge of the first display so that the first display can be rotated about the X axis. The second bracket is rotatably connected to a side edge of the second display so that the second display can rotate around the X axis. When the processor determines that the first display and the second display are in a spliced state, the display card extends the display image of the first display to the second display.

Therefore, the display card can calculate the color conversion formula A according to the above formula. By using this color conversion formula A, the adjusted first lookup table can be adjusted to the first modified lookup table: among them Represents the first correction lookup table.

In this embodiment, the color conversion formula A can be expressed as a gain and an offset to the first lookup table, as shown in the following formula:

The first correction lookup table is stored in the display card, and the colors displayed by the subsequent display 104 are processed by the first correction lookup table to show the real-world colors, and the correction of the display 104 is completed.

Similarly, the display 106 is calibrated based on the corrected display 104. The WRGB value of the display 106 sensed by the color sensor 606 can be expressed as: among them Represents the color processed by the gamma value of the display 106, A second lookup table representing the display 106.

The display card of the electronic device 100 adjusts the second look-up table by using another color conversion formula B to correct the WRGB value of the sensed display 106 and the WRGB value of the corrected display 104 to be consistent. The formula is as follows: among them Represents the WRGB value of the corrected display 104 (i.e. ).

Therefore, the display card can calculate the color conversion formula B according to the above formula. By using this color conversion formula B, the adjusted second lookup table can be adjusted to a second modified lookup table: among them Represents a second correction lookup table.

In this embodiment, the color conversion formula B can also be expressed as a gain and an offset to the second lookup table, as shown in the following formula:

The second correction lookup table is also stored in the display card. The colors displayed on the subsequent display 106 will be processed by the second correction lookup table to show the real-world colors, and the correction of the display 106 is completed.

It is worth noting that the display 106 is calibrated according to the calibrated display 104 instead of the ambient light. This is to minimize the correction error between the display 104 and the display 106 so that the colors between the display 104 and the display 106 are consistent.

FIG. 7 is a schematic diagram of a part of the hardware architecture of the electronic device 100 for calibrating a display according to an embodiment of the disclosure. The color sensors 604 and 606 of the color sensing device 602 individually sense (as indicated by arrows) the colors of the display 104 and the display 106, and then use the sensed color data (eg, the ambient WRGB value, the WRGB value of the display 104) And the WRGB value of the display 106) are transmitted to the processor 702. After the processor 702 transmits the sensed color data to the display card 704, the display card 704 uses the sensed color data to calculate a color conversion formula (such as the color conversion formulas A and B described above). The color conversion formula can be used to adjust the look-up table. The adjusted look-up table (including the color conversion formula) is fed back and recorded in the driver 706 of the display card 704. The image (color) to be displayed subsequently can be processed by the adjusted look-up table, so that the colors displayed between the display 104 and the display 106 are consistent.
