Abstract
A data driver can include a white data voltage output circuit having an Ath channel for outputting a first white data voltage and a Bth channel for outputting a second white data voltage different from the first white data voltage. The data driver can further include red, green, and blue data voltage output circuits configured to output a red data voltage, a green data voltage, and a blue data voltage, respectively. One of the Ath channel and the Bth channel can operate in a first driving condition, and the Ath channel and the Bth channel can operate together in a second driving condition.
Claims16
A data driver comprising:
- a white data voltage output circuit having an Ath channel for outputting a first white data voltage and a Bth channel for outputting a second white data voltage different from the first white data voltage;
- and
- red, green, and blue data voltage output circuits for outputting a red data voltage, a green data voltage, and a blue data voltage, respectively,
- wherein one of the Ath channel and the Bth channel operates in a first driving condition, and the Ath channel and the Bth channel operate together in a second driving condition.
A light-emitting display (LED) device comprising:
- a display panel configured to display an image;
- and
- a data driver connected to data lines of the display panel,
- wherein the data driver comprises:
- a white data voltage output circuit having an Ath channel for outputting a first white data voltage and a Bth channel for outputting a second white data voltage different from the first white data voltage;
- and
- red, green, and blue data voltage output circuits configured to output a red data voltage, a green data voltage, and a blue data voltage, respectively, and
- wherein one of the Ath channel and the Bth channel operates in a first driving condition, and the Ath channel and the Bth channel operate together in a second driving condition.
