DISPLAY DEVICE
A display device is disclosed. The display device of this invention includes: a display panel; a plate whose one side is attached to the rear surface of the display panel; a module cover including a forming area that is projected and recessed in at least some part to keep a distance from the plate; and a housing attached to the module cover. According to the present invention, it is possible to minimize heat transfer towards the display panel by including a module cover where a forming area is provided to keep a distance from a plate.
DISPLAY DEVICE AND DISPLAY METHOD
An image signal line driver circuit includes first to third source drivers and fourth to sixth source drivers, which are respectively cascade-connected. The output duration of data signals that are provide to these source drivers is increasingly short on the source drivers that are connected further downstream (that is, the amount of pixel data to be output to the next stage is increasingly small). This reduces the power consumption and heat generation of the overall device. Moreover, the phases of the data signals are shifted, thereby reducing EMI. In this way, when a plurality of image signal line driver circuits are cascade-connected, heat generation and power consumption in each driver circuit and/or EMI therebetween is reduced.

The estimation of the temperature is performed based on a result of learning a relationship among the input image data, the lighting ratio and a temperature measurement value of the light emitter, and a temperature measurement value of a previously designated light-emitting element of the image display.
