Abstract
(EN) Provided are a backlight module and a display apparatus. The backlight module comprises a plurality of tilted backplates; light-emitting devices in the backplates are used to emit light under the control of a high-level power signal and a low-level power signal; the light-emitting devices comprise a first light-emitting device located in a region in which adjacent backplates are tilted, and a second light-emitting device located in other regions of the backplates; and in at least one backplate, a first high-level power signal corresponding to the first light-emitting device is greater than a second high-level power signal corresponding to the second light-emitting device.
(FR) Un module de rétroéclairage et un appareil d'affichage sont divulgués. Le module de rétroéclairage comprend une pluralité de plaques arrière inclinées ; des dispositifs électroluminescents dans les plaques arrière sont utilisés pour émettre de la lumière sous la commande d'un signal de puissance de haut niveau et d'un signal de puissance de faible niveau ; les dispositifs électroluminescents comprennent un premier dispositif électroluminescent situé dans une région dans laquelle des plaques arrière adjacentes sont inclinées, et un second dispositif électroluminescent situé dans d'autres régions des plaques arrière ; et dans au moins une plaque arrière, un premier signal de puissance de haut niveau correspondant au premier dispositif électroluminescent est supérieur à un second signal de puissance de haut niveau correspondant au second dispositif électroluminescent.
(ZH) 本申请提供一种背光模组和显示装置,背光模组包括拼接的多个背板,背板中发光器件用于在电源高电位信号和电源低电位信号的控制下发光,发光器件包括位于相邻背板拼接区域的第一发光器件、位于背板其他区域的第二发光器件,至少一个背板中,第一发光器件对应的第一电源高电位信号大于第二发光器件对应的第二电源高电位信号。
