Problems solved by technology

[0009] In this related art, since it takes a lot of time and cost to perform offset correction on the offset characteristics of all the analog-to-digital converters at the same time, and this consumption of time and cost makes it difficult to Extrinsic compensation is performed on digital image data, so the extrinsic compensation may be wrong, and thus image problems such as dark blocks may occur

Embodiment Construction

[0025] Reference will now be made in greater detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. in any available

[0026] Since the embodiments described in this specification and the configurations shown in the accompanying drawings are preferred implementations of the present invention

[0029] The display driving apparatus 100 includes source drivers 10, 20 and 20 which provide source driving signals to the display panel 200

[0030] As the display panel 200, a liquid crystal panel, an organic light emitting diode (OLED) panel, or the like may be used. on the display panel

[0032] When the timing controller calculates the characteristic value of the pixel, the analog data with the source drivers 10, 20 and 30 can be used.

[0033] The analog-to-digital converters 12, 22, and 32 provided in the source drivers 10, 20, and 30, respectively, may have different

[0034] Therefore, in order to accurately cal...

Abstract

Provided are a display driving device capable of simplifying correction of characteristic deviations in analog-digital converters provided in respective source drivers, and a display device including the display driving device. The display driving device includes a first source driver and a second source driver adjacent to the first source driver, and the first source driver and the second source driver share a sensing line for sensing pixel characteristics of the display panel. At least one of the sensing lines respectively samples pixel signals of the same pixels, and respectively converts the sampled pixel signals into digital data.

Description

Display driving device and display device including the same technical field [0001] The present invention relates to a display device, and more particularly, to an analog signal for correcting a source driver A technique for characteristic deviation between digitizers. Background technique [0002] Generally, a display device includes a display panel, a source driver, a timing controller, and the like. The source driver will sequence the The digital image data provided by the controller is converted into source driving signals, and the source driving signals are provided to the display panel. source The electrode driver includes one chip, and a plurality of source drivers may also be configured in view of the size and resolution of the display panel. [0003] In a display panel, the characteristics of pixels may vary according to changes in time and temperature. [0004] In order to improve this change in the characteristics of the pixels with respect to the digital im...
