Problems solved by technology

In this case, if each of the plurality of slave devices includes a clock circuit inside, the size of the display device may increase in the entire system
[0005] In addition, since clock circuits also consume power, power consumption may increase in proportion to the number of clock circuits provided

Embodiment Construction

[0043] figure 1 is a diagram showing the structure of a display device according to an embodiment.

[0044] refer to figure 1 , the display device 100 may include a panel 110 , a source sensing IC (SRIC) 120 , a gate driving IC (GDIC) 130 and a timing controller (TCON) 140 .

[0045] A plurality of data lines DL and a plurality of gate lines GL may be arranged on the panel 110 , and a plurality of pixels may be arranged on the panel 110 . A pixel may include a plurality of sub-pixels SP. Here, the sub-pixel may be a red sub-pixel (R), a green sub-pixel (G), a blue sub-pixel (B), a white sub-pixel (W), or the like. One pixel can be configured as an RGB sub-pixel SP, an RGBG sub-pixel SP, an RGBW sub-pixel SP, or the like. Hereinafter, for convenience, description will be made assuming that one pixel is configured as an RGB sub-pixel SP.

[0046] The source readout IC 120 , the gate drive IC 130 , and the timing controller 140 are devices that generate signals for displayin...

Abstract

The invention relates to a display device and a micro-controller unit for data communication. The present disclosure relates to a data communication between a micro-controller and a source readout circuit, does not require a clock circuit of a slave device, and thus, allows the size of a slave circuit and power consumption to be reduced.

Description

technical field [0001] Embodiments relate to techniques for data communication between a microcontroller unit and a source sense integrated circuit (IC). Background technique [0002] A large amount of data can be sent and received between internal circuits in the display device. These data may include image data containing information on images to be displayed on the panel, or control data for controlling internal circuits to display these images. Thus, a protocol for sending and receiving data is also required. For example, the protocol may include details about whether communication is to be carried out using a synchronous or asynchronous method, or details about the sequence in which data is exchanged if a synchronous method is used for communication. [0003] Generally, data communication between internal circuits of a display device may be based on a serial peripheral interface (SPI) or an inter-integrated circuit (I2C). In the SPI or I2C scheme, if the clock is del...
