LG Display May Supply LCD Panels to Sony

April 15, 2009

LG Display is in dis­cus­sions with Sony to sup­ply LCD pan­els accord­ing to indus­try sources. LGD began nego­ti­at­ing with Sony early this year to pro­vide 32″, 37″ and 42″ LCD TV pan­els. Currently Sony pro­cures 60% of its large-size LCD pan­els from its joint ven­ture with Samsung called S-LCD. AU Optronics (AUO) and other Taiwan-based LCD sup­pli­ers have been ful­fill­ing the rest. Detailed analy­sis after the jump.

This is inter­est­ing news since Sony has invested heav­ily in S-LCD, its joint ven­ture with Samsung and has nego­ti­ated another LCD joint ven­ture with Sharp called Sharp Display Products. Another inter­est­ing point is that both Sharp and Samsung man­u­fac­ture LCDs based on VA (Vertical Alignment) tech­nol­ogy that behave sim­i­larly. Sharp’s ASV (Advanced Super View) and Samsung’s S-PVA (Super Patterned Vertical Alignment) LCD pan­els are both based on VA. However LG Display mainly uses IPS (In-Plane Switching) tech­nol­ogy for large LCD TV pan­els. IPS Alpha as well as Hitachi man­u­fac­ture LCD pan­els using IPS tech­nol­ogy. IPS is known to have great view­ing angles, superb color fidelity with lit­tle to no color and con­trast shift at wide view­ing angles. But IPS does not have extremely high con­trast ratios when view­ing from dead cen­ter. Brightness lev­els are not cornea-burning and can suf­fer from not shal­low blacks com­pared to VA pan­els. With the advent of LED back­lights and local dim­ming this has all changed since local dim­ming tech­nol­ogy can make blacks very deep because the light behind the black is turned off.
